[mythtv] Error in win32-packager.pl?

[MarcT]

I was able to fix the issue with compiling myththemes, was simpler than I
thought it would be.

However now I get the following error

Parsing [Files] section, line 986

Error in C:\mythtv\build\isfiles\mythtvsetup.iss: The process cannot access
the file because it is being used by another process.
Compile aborted.

So people don't say oh your mythtvsetup is older than your last build...
there is nothing in the setup folder. It bombs before it can create one.
Looks like inno setup is reading from mythtvsetup.iss and trying to write to
it, which leads me to believe the issue is in the mythtvsetup.iss file.
However, that is beyond me.
