Hi Michael,
I'm glad to hear you are not being prevented from creating reports.
If these messages concern you, and you do not have any other programs that use Crystal Files, you could always try renaming the \windows\crystal directory and reinstall Quik Reports for Windows. We do not install the 3 files you listed, so another program must have put them there. Of course if you do this, make sure to note any printing problems from other programs in case any of them use Crystal.
The closest file I found that we install is PDIRSSI.DLL in the \windows\crystal directory. I have files p2irdao.dll and p2ctdao.dll, which were installed by Crystal Reports 5.0.
