Two additionals infos:

The two dlls don't have the same name but are stored at the same location

For instance:

C:\Support\Server32.dll
C:\Support\Server64.dll

and the tlb are stored in both dlls.

Hello,

We have another question related to this problem:

Can a 64 bits process (or dll) is able to access a TypeLib embedded in a 32
bits dll (or the opposite)?

Using ProcessExplorer, we saw a 64 bits dll listed in our 32 bits process
(and, yes, we are sure that this dll is 64 bits).

Best regards,

Olivier.

Why would you want to?

On Windows64 32-bit applications can not load 64-bit Dlls and 64-bit
applications can't load 32-bit Dlls. But as there is nothing in programming
that is impossible, I suppose one might come up with a way to extract TypLib
information out of any file. But what would you do with it?
