After having a lot of problems with a new installation of SW 2010 we decide to unistall and perform a clean installation... now we can not complete the installation, since about 18% into de installation process we geet the following error:

Internal error: The Windows Installer for this product component did not run as expected: set_Reg_VSTAHost.

Any ideas on how to resolve this issue?  On internet you can see many references to this problem (do a search just on "set_Reg_VSTAHost") but no reference at all on the SolidWorks WEB...

I believe the problem is created by the Visual Basic Tools for Applications previously installed with the original installation (which apparently the unistaller do not remove)...

One of this days, SW will provide us with installers that really work...

We will appreciate any help on this.
