The first and most important step. We warmly invite to install the telco App and  check you computer

VIPERLAB Webinar is based on the lectures/presentation offered by speakers/presenters and the utilization of MS Teams or Adobe Connect ®   e-conferencing platforms widely diffused in several organziations to propose on line seminars, conferences and e-learning.

  • A single platform to plan, deliver, and track to cover  pre-event and post-event workflows.
  • to assure  End-to-end campaign management and Complete eLearning solution
  • the platorm runs on premises in CRESCO HPC, to assure Comprehensive security: from application security to network security to cloud infrastructure security for hosts, participants, and confidential enterprise information. 

The platformhas recently improved its performance after the difficulties encountered in the past two years becouse FlashPlayer was no longer be supported (since December 2020) . Provision for the use of other platforms (Zoom, MS Team, Meet, GoToMetting,etc) is also considered.

NO special Hardware or Software is needed for either the presenters and  the audience but.....

Please  read carefully the instruction below:

NOTE: Whether you are a new and inexperienced user in web-conferencing or you are askillful but you normaly use other webconferencing systems than Adobe Connect we suggest  you to  pay attention to the following information.

These advices come back  from the lessons we learned by interacting with more than 150-200 speakers and more than 5'000 live participants, and they will help you in avoiding commonplace troubles.




Following steps help both speakers and participants to get skills in using our webinar platform.

Speakers should also refer the specific section reserved to them to learn how to turn on/off web cam/microphone and to use  them properly.


Check you computer :

  • Update the operative system for your computer and update your web browser (Internet Explorer, Firefox, Chrome, Safari, etc) particularly if  you don’t  do this frequently.  It will be a pity that the operative System (OS) or the browser of your computer  will start to update during the webinar by blocking your computer and your activities  for 10-15 minutes or more
  • Install your multimedia tools (webcam, microphone) if you have not already done it yet:
  • Participants need of both the reproducing device i.e.  loudspeakers and/or  headset. and they don't need of  web cam/microphone.
  • Speakers/presenters must use  both reproducing (better headset* for them)  and  recording device (microphone) ). They  also  need  of a optional webcam is warmly suggested

*For the speakers/presenters  the headset works better than loudspeakers becouse last ones couple with microphone by producing annoying sounds effects and noise.

Pls  check that your audio  works properly . Refer to following paragraph "audio setting and troubles"


Install Adobe Connect App

Often weconference systems ask you to download or update Add-in,These are devices and piece of software that can be added to your computer to give extra features or functions. And this also happen when you use Adobe Connect.

Adobe Connect 11 meetings applications are backwards compatible with earlier versions of Adobe Connect. Please note that although there is currently no application for Linux, users on Linux (Ubuntu, Red Hat and OpenSUSE) can still attend, host, or present in meetings in the browser.


This link sometime shows difficulties to check the speed connection. We are trying to fix it. But don't take care of it.
Check your  internet connection speed by the instruction below


Check   internet connection speed and its quality

  A rock-solid internet connection is the essential prerequisite for any effective remote conferencing.
Wi-Fi is obviously more convenient than wired Ethernet cables, but Ethernet still offers significant advantages in stability and speed, and we warmly reccomend speakers to use LAN/Ethernet connection with assigned IP-Internet Protocol address, than a Wi-Fi connection with dynamic assigned IP. A opposite we leave the participants free in chosing their connection. 
  • Internet datas are carried around in small chunks called packets.  Connections speed is only a part the of the whole picture. The other one is  the connection stability. If your connection experiences packet losses your browsing slows down, and it causes a decrease in audio/video quality..
  • You can use a speed test like  http://www.speedtest.net/   or any other one you love to test both uploading/downloading speed and PING- Packet INternet Groper .
  • Connection speed > 0.4 Mbps (400 Kbps)  or  faster for both incoming/upcoming are welcome, particularly for the presenters/speakers becuse they need higher data transfer speed then participants. PING lower than < 50 ms  welcome.
  • How to Ping more deeply??? Pinging simply sends a data packet to a remote computer, asking that computer to respond. If it responds, it records information about that response for you to elaborate and review results. You can do it  by yourselves by using PING command specific for your operative system and by dedicating the test to our web site. The tests you should perform  depend from your operative system.You can find more information here.
  • If you could meet troubles, let's know and we will be  very  happy to assist you. Please forward us an email by indicating any useful detail about the  troubles you are facing.




Adobe Connect Test link and troubleshotting page


Adobe Connect also offers @ Adobe meeting Test, a web page you can use to check your connection  and install add-ins & plug-ins on request.  The suggested  link checks following steps:

  1. Access to Adobe Connect
  2. LAN/DSL speed test and bandwith
  3. Installed Add-in in your computer

This page also include useful technical information and troubleshoting.


How to access?

For more information how to access to the webinar room and how interact with the speakers, see the specific section

We summarize here that:

  • You will receive your credential to access based on a Uniform Resource Locator (URL), commonly informally termed a web address. You could also receive an  alphanumeric code named room passcode, when restricted access is required (see access section)
  • When you will receive URL / room passcode  by email, or if you will access to this inormation  by logging in as VIPERLAB Knowledge Exchange platform registered user


You should  utilize your credentials to  log-in asap  and ckeck that everything works properly, and inform  us  by email   if you could meet troubles.



Check  your listening device (audio)

  1. After logging in to the event virtual room (webinar room) check your  audio (loudspeaker/headset)   by using   menu Meeting > Audio Setup Wizard > test audio (see photo)
  2. ~60-30 min to start you will also perceive some voice, sounds produced by speakers/assistents.
  3. Adjust the loudspeaks/headset volume if you could need of it.
  4. During the presentations and at the end of each lecture, partecipants can interact with  both chair and speakers by "live chat" (pls utilize "chat pad". You will find it usually in the right side or central area of your screen.




 Take care that if you could not  listen any sounds or you could listen it  by a very low volume, you have  probably left the volume of  your loudspeakers/headset at very low level.

  1. Adjust it by finding icon loudspeaker. It  is usually placed in the right-bottom  side  of your screen. Click by mouse (left button) on the loudspeaker icon and check you volume level.. -- >
  2. If you will  click   on the same loudspeaker icon  by right mouse  button (instead then left button)  you can have access to a more complete menu to control the Volume Mixer of your computer  for both  reproducing tools (loudspeakers/headset) and  recording tools (microphone). See photo on right side.
  3. You can check and you can select which is your reproducing channel (output audio).  Adobe Connect will use the reproducing  channel (output sound) that you operative system use by default.
  4. Change reproducing  channel, if you would change it or if you are finding  troubles in utilizing  the default reproducing channel  is set by your computer. 
  5. VIDEO/MICROPHONE is authorized to Speakers/presenters only but assistant/chair can  also exceptionally authorize the access by
  6. microphone/web cam for the registered partecipants on their specific request.

If participants meet audio difficulties/troubles, they can  contact us very quickly by adobe connect chatemail, phone , skype (time limit ---> 30 min to start)




Laptop or a Desktop PC?

People don’t use desktop as in the past, and speaker has probably a laptop of higher quality than his/her  own desktop PC. We leave always the final chose to the speaker and  we will check that speaker's computer works properly

Pro -- > laptop is the computer speaker probably normally use . A  new laptop is always updated and it has always  an high quality web cam and microphone. 

Cons-- > the optical quality of an external HD web cam use on a desktop PC is often of higher quality that a laptop web cam. Furthermore If the speaker tilt the view of his/her screen, speaker also  tilts the view of his/her  web cam. And  very old laptops have often  low quality microphone, low quality  web cam and noisily  processor fan. This produce low video/audio quality.

Not depending from the speaker chose, as already indicated above, we warmly suggest to update the OS-Operative System and Web-browser 1-2 days to the event and once again few hours before starting. Often  multi-platform ICT  companies update their facilities and software overnight. And it will be a puity that the Operative system updating will block your computer.

Check asap your speed connection, FlashPlayer and add-in by link indicated above. Check reproducing audio (information in paragraph above) and your microphone and webcam  (see sections below) above).


Install Adobe Connect  APP & ADD-in:

This step is very important for the speakers/presenters becouse they need of a wider control of the teleconferencing system than participants. Add-in is a term used, for a software utility or other program that can be added to a primary program to improve its functions. Adobe Connect Add-in allows meeting presenters and hosts to share their screen, control other users' screens, and upload their files to meetings.

here: https://helpx.adobe.com/adobe-connect/connect-downloads-updates.html



How to share documents/files? How to show them on video to all participants

SPEAKERS/PRESENTERS share their document  (usually power point or pdf files) by selecting different "sharing option" offered by the drop-down menu appearing on  the computer screen (see photo below).The speakers can also propose (live) experiments or they can show equipments/ testing/ characterization procedures/ by using video, web cam 


Access to  Webcam/Microphone Is usually offered to Speakers/Presenter only

Mouse Click on microphone or web cam icon to turn on/off  them

By mouse clicking the icon colour changes from grey to green. If you push once again on the icon you can force microphone  in stand-by condition  (icon crossed by a bar). To adjust microphone volume you can have acces to the volume pad by clicking on the arrow next to the icon and by selecting Adjust  Microphone volume



  1. As mentioned above, speakers can check by themselves microphone by menu Meeting > Audio Setup Wizard > test audio (see photo above) but audio quality of speaker  microphone is very important and CHEETAH assistants  will check this properly before starting the webinar.
  2. Microphone is directly turned on/off  or in stand-by by speaker/presenter clicking on microphone icon.
  3. We warmly recommend to turn always off microphone when you doesn’t need of it  in order to avoid  echo/noise during other presentations
  4. We warmly suggest you to use headphone/headset and digital microphone. They  produce less audio troubles than loudspeakers and analog microphone.  And always a HD web cam has  a high quality  digital microphone . 
  5. If speaker(s) present their webinar(s) in a conference room, please always  pay tightly attention to the room noise and resonance/echo. In fact loudspeakers easily couple  with microphone and this could  cause a  damned annoying sound resonance effect, particularly when audio system is  directly coupled to computer line-out.
  6. keep away microphone from the loudspakers to avoid that sounds could be acustically coupled (echo).
  7. The quality of  speaker(s)  microphone and the practice in its  use is very important  for a successful webconference and We always offer  training session to any interested  speaker/event chairperson(s)
  8.  Learn from TV newscast more than talk show Telco isn’t a phone call. If more than two speakers turn on the microphone and they don’t synchronize their pause by speaking all togetherthe sound  is coupled so deeply and frequently modulated in volume that terrible noise can be produced , and  the speakers/presenters voice is continuosly break. In this circumstance audience cannot listen properly the speakers' voice.
  9. We also warmly suggest presenters/speakers to reduce the volume level for the system  signal allert (email arriving, click by mouse, etc) as opposite everyone will listen your system alerts You can access to mixer pad by loudspeakers icon (see section above).



  1. Webcam needs of a two steps process to be switched on.
    1. First of all by mouse clicking  on "web cam icon". The web cam is turned from off to stand-by mode (video preview windows) and the web cam icon change from "grey" color  (turned/off)  to green color (turned/on)
    2. Further, you must push "start shading"  bottom  you can find in the web cam "Preview" video windows
  2. Utilize an HD web cam (1440p, 1080p o 720p)
  3. Avoid relevant light in your backWeb cam will not work properly in this condition



If you will find  difficulties please contact us  by email, phone  (time limit ---> 30 min to start)

  2. http://helpx.adobe.com/adobe-connect/kb/configuring-connect-professional-listen-additional.html

Probably your port firewall/proxy configuration is not meeting the following:

  • Port 80 open TCP/UDP for incoming /outcoming traffic
  • Port 1935 open TCP/UDP for incoming /outcoming traffic

In fact some corporate firewall/proxy server blocks port 1935 for incoming and outgoing network traffic
