Error after installing VSI 5.5 on win7 PC's

Hi,

I hope somebody can help. After upgrading VSI 5.4 to 5.5 on my workstation, the solutions enable connection does not work anymore...

I get error: Connection failed. Error: An error from a sub-library call occurred.

I have to say, that I did select to install the SE 7.6 component...

Also on 2 other PC's where I performed a clean install, I have the same error...

Any ideas?

Tnx in advance !

Peter.
