Hi , I am using the 17.2 version, Vista 32 bit. When I try to run the CF. I only get error message:

"The application has encountered an unexpected problem and will now terminate:

Aborting due to unexpected error:
comm::error: AppWindow::initialize - Error waiting for viewer connection from engine:

Please report this error, along with the circumstances in which it occurred.

The following information may be useful to CFX support:

Unexpected error: Aborting due to unexpected error:
comm::error: AppWindow::initialize - Error waiting for viewer connection from engine:".

another message:

Does someone know where could be problem?
How should fix this problem?

What exactly did you do when that message appeared?
Have you tried restarting your windows and starting CFX again?

Can you update to a newer windows version (and newer CFX version)? I don't think Vista, and even worse: 32bit, is supported...
