What are these files for?

What are these files for?
stdole2.tlb
oleaut32.dll (600kb)
olepro32.dll
asycfilt.dll
comcat.dll

We're required to include them with our setup, however I found that some of them (oleaut32.dll) are included in all version of windows since Win95.

Are these files needed for setup extraction/installation of are they just VB runtimes?

Since oleaut32.dll is pretty big and came with Win95 - WinXP, can I safely exclude it from my setup programs?

No. Don't exclude them.

Those file have versions. Newer versions have newer interfaces which new VB6.0 expects to find in them.

This all has to do with COM objects - servers. Those dll and OCX's all provide COM servers that expose dozens of interfaces. Rather than trying to save 5 MB on your distribution and risk a mess later on, leave them in there. Or you'll get wierd errors like 'Interface not supported'

Thanks Jim
What about msvbvm60.dll?

I found out that it's included with Windows NT, 2000, ME & XP

Do I still have to include this file for setups on the above Windows?
