Missing DLLs?

[botbswco]

Installed Ver 12.5 on XP box. Built new VB installation package. Deployed package to Win 7 and Win 8 boxes successfully.____Moved devel environment from XP to Win 7. Installed ver 12.5 on Win 7/64 box. Application and reports run fine both from within VB6 and from compiled .exe. ____Then attempted to rebuild VB installation package. Three DLLs are not found anywhere on the Win 7 box:____MFCANS32.DLL, OC30.DLL, THREED32.OCX____Since the app runs OK on the devel box without the DLLs, are they really required?______One workaround for application deployment is to install the XP version and then copy any updated VB application files. That is messy.____Preferred option is to somehow manually install and register the DLLs on the devel box so they can be included in the package.____Any other suggestions or solutions?____Thanks__

I believe these are all Microsoft files. They may no longer be necessary. If things seem to be working OK without them, I wouldn^t worry.
