Adabas Manager Communication Client is not running

I’ve installed the Adabas Community 8.3.2 on Windows 7 x64 and I’m getting the following message in Adabas Manager:

“Adabas Manager Communication Client is not running; or specified host name / port number (localhost:4980) of Adabas Manager Communication Client is invalid.”

No Software AG services appear to be stopped.

I tried to install it on a real laptop and multiple virtual machines - the result is always the same. No solution to this problem could not be found.

Any ideas?
