so what is the diffrence to TCS3? I could not make out any new features/versions, but perhaps the website has not been updated yet. The features page was still titled TCS3.
Please excuse for posting unter Adobe Technical Communications Suite > Technical Communications Suite installer. I am aware this pops up in the product forums as well but I did not know of a better place to post.
AFAIK, the 3.5 version updates Captivate to 5.5 (see: http://help.adobe.com/en_US/captivate/cp/using/WS287f927bd30d4b1f473b1 cf312ee14e8531-8000.html) and includes the patches for the rest of the products. A $99 upgrade from TCS3.
Arnis' message is absolutely correct, but additional info:
The Upgrade is free for customers with maintenance.
For German customers: http://www.squidds.de/tcs or
