I'm using Crystal 8.5, But I think it works

I copied the next dlls to Win Dir

crxf_pdf.dll
P2bxbse.Dll
p2lodbc.dll
p2ssql.dll
u2dapp.dll
u2ddisk.dll
u2dmapi.dll
u2fwordw.dll
u2fxls.dll

And I registered (using RegSvr32)
Craxdrt.Dll
crtslv.dll
crviewer.dll
ExportModeller.dll

I think it wil help you
