"Bad Image" problem with Heat in Wix 3.0 with typelibs

Question

When using heat (from Wix 3.0.4805.0) to generate Wix documents off of a typelib that's generated by Visual Studio, I have been getting an error. A window pops up that says:

'heat.exe - Bad Image'

The application or DLL c:\path\to\file.tlb is not a valid Windows image. Please check this against your installation diskette.

But then after we press 'ok', it continues on and successfully generates

It looks like this bug report on the wix bugboard says it was fixed in a release previous to mine, but it seems not to be. They say that the error occurs because it tries to load it as a DLL first (which fails) but then continues on to do the right thing.

This is happening on Windows XP SP3.

Anyone know of a workaround for this?

Answer 1

Try a later build. There have been significant bug fixes to heat since 4805 build.
