> What to do with this error while compiling Setup project?
"An error occured while validating. HRESULT = '80040155'"
Is this a standalone program or does it use other custom dll's?
Do you get this error during compilation, or when your programs starts to
execute.
I think that this is some dll that you load that either is not installed or
is the wrong version.
Another possibilty is that you launch this application form a network
drive.(maybe comple directly on a nework drive?)
