View Full Version : VS 2010 & IS 2011 - "Catastrophic failure" in project properties.

09-15-2010, 09:05 AM
My team is migrating from using the built-in visual studio setup projects to Installshield. I created a test solution to try things out and it didn't start out well...

When adding an installshield 2011 project (happens w/all types I've tried) the property page for all other projects in the solution give an error (solution will also not build):

"Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))"

This happens just by adding the IS project...I don't even have to set project outputs in the IS project.

See attached photo.

Same Problem. When I apply the patch i dont get that error anymore, rather, everytime I click the properties page visual studio needs to restart. I have tried re registering those 2 dll's and restatrting the machine. Nothing works. Any Ideas?

That seems to be a Visual Studio bug. I believe that a beta of SP1 for Visual Studio 2010 is available now, at least to MSDN subscribers. If you have access to the beta, you may want to try installing that and see if the problem is resolved.
