It did not matter what version of the Add-in I used, they all behaved the same way. The Connect add-in would lauch, but stay as a small window. I ran into a similar situation will testing Windows 7 clients with Adobe Connect (7.0/7.5/8.0/8.1) I had found on another forum that you need to ensure Tools > Internet Options > Advanced > Check for Server Revocation is DISABLED. This is for a gov't client so these machines are locked down according to DISA Win 7 STIGs. Now if I run IE as an administrator, the Adobe Connect plug in will launch successfully and I can then share my desktop / participate in the room. I have run the Adobe Connect Pro Connectivity Test and it is 100% successful. Regardless, I tell it to install on my system, it goes through the install process (installing to my App Data folder), launches the Adobe Connect plug in-in and I am left with the same white/gray box. Upon entering the room I am prompted to install the Adobe Connect plug in in the event I wish to share my screen (even though the plug in is already installed). This works successfully but of course I am limited and cannot share my screen.

In digging through the forums I found the trick of manually pasting the URL for the meeting room followed by the ?launcher=false, which results in you running the room from within the browser. I am left with an Adobe Connect box that is white/gray. The plug in says 'Adobe Connect' in the top left hand corner and there is a white box where the meeting should open with Flash but does not. In trying to enter a meeting utilizing IE on my user account, a separate IE Tab pops open with the URL for the meeting name followed by the Adobe Connect plug in (the previous page that had the URL for the room then closes). We are working in a Win 7 environment (redirected App Data), utilize IE 8 and Adobe Connect Add-in 9.4 r80. I have dug through these forums in addition to a number of other resources in search of a resolution for the problem I am facing.
