Hi, I have a dll that is declared as Custom Action type 1 and is loaded into the binary table.  I keep having this error message and don't know where to begin looking.  Error message is "There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run. Contact your support personnel or package vendor. "

Any help is greatly appreciated,
David

Use Dependency Walker to check if the DLL can be loaded on that operating system at all. It may be missing some dependency.
Or the function name you specified may be wrong, or the exported function name in your DLL may be mangled (you can see this in Dependency Walker, too)

I had this same problem and it turned out that when I was adding the custom action from the dll in the Merge Module, I was pulling the action from the wrong source.
