I was previously using Crystal this way

reportapp=createobject("Crystal.CRPE.Application")
orpt = reportapp.OpenReport(tcRPTName)
orpt.PREVIEW("", 0,0 , THISFORM.foxhwnd.Width-15, THISFORM.foxhwnd.Height-25, 33554432, THISFORM.FoxHwnd.hwnd)

and I had a couple of dbi tech activex's on the main form.
These activex's required version 6 of mfc42.dll
In my app install on a computer that had win98 first ed. for OS
it needed the newer mfc42.dll.
when that was included in the install I would get a error
registering cpeaut32.dll. But if no mfc42.dll was in the install
I would get no error for registering cpeaut32.dll, but the other activex's would not register.

The RDC way of using Crystal Reports - I now have no activex registering errors during my app install with the newer mfc42.dll.

Thanks again
