#1142 Can't open project with WixUIExtension dependency

[Tim Rayment]

I’ve just installed the latest wix3.msi (3.0.3097.0) on XP SP2 with VS2008 rtm and am getting the following error on attempting to open a solution containing a WiX project which includes a dependency on WixUIExtension.

Error HRESULT E_FAIL has been returned from a call to a COM component.

The project is then marked as unavailable in the IDE.

Command line builds still work with this WiX version.

Hello,

I had the same problems, but it was not a problem of WixUIExtension! I had some subdirectories within my project:
After removing from the wixproj...

<itemgroup>
<folder include="NewFolder1\">
</folder></itemgroup>

... and after CLOSING COMPLETELY DevStudio (yes, just reload doesn't work!!) and reopening the solution, I could open it normally without E_FAIL!

I then just inserted my previously removed resources to the projects' root, and it works for me.

I also had this problem, and also found it to be a result of having subdirectories. You can have subdirectories, but you can't include them in the VS2008 project. I'm referencing WixUIExtension in the project and this isn't causing any problems.
