Where's the harm in resolving the imports of the builtin?
In this case, the app has already loaded and used oleaut32 before it
gets around to asking about its version.
I tried this patch, and unreverted the GetFileVersionInfo(Size) patch,
but juno still isn't happy. With the native dll present, the app asks
for its version info and gets the builtin. The ver trace looks a little
strange to me - maybe it will make sense to you?
About.exe returns the builtin oleaut32 version, but _only_ if the native
oleaut32 is present (if I move it away, About.exe gets size 0), and only
if it is given the native dll's filename. Give it the builtin filename
and it gets size 0. I think the latter is probably not a problem, but
it seems strange to me.
It always astounds me how worked up msdose windose programs get about
Hmmm, msdose has a fairly systematic facility to lie to programs - IIRC,
even to a different lie for each program - about version information.
Maybe we need something along those lines (gaaa!). I am afraid juno
actually wants to see verbatim the whole version block from oleaut32 -
the install program for it does install one, right over whatever was
there, for all it cares, so it may well consider any deviation fatal.
I haven't looked at it in depth yet, but I may have to.
