Hi,

I have an installer project which installs my application and it's dependencies, which used to run fine on XP.

This project has some Custom Actions that register a service.

I can register the service manually using elevated command line.

But the custom action hangs.

I have created a sample installer project with some empty custom actions and it hangs as well.

My conclusion is that Vista has some issues with Custom Actions.

Needless to say is that the Installer is run elevated, of course.

Also each time I get this hang I have the following error in the EventViewer :

Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x800706f7.

Does anybody have any input ???

P.S. My Custom Action project is in C#.

Thanks!

Lady_A.
