We are facing the need to concurrently support an existing product that
currently is compiled under VC++4.2b and newer versions that will be
built under VC++ 5.0 or 6.0, depending.

It would be convenient to be able to build either on the same
workstation.  Can VC 4.2b be installed on the same workstation as the
later versions, or will we run into problems like conflicting DLL
versions in %WINDIR%\SYSTEM32?

Thanks,
Dan
