Below is the section of my Inno Setup script that pertains to the file export requirements of Crystal Reports 8.5 All you really need to know is the file information, but I'm pasting it as-is:
; begin Export Destinations
Source: C:\WINDOWS\Crystal\u2d*.dll; DestDir: {pf32}\Seagate Software\SI\X86; Flags: sharedfile
Source: C:\WINDOWS\Crystal\u2d*.dll; DestDir: {win}\Crystal; Flags: sharedfile
; end Export Destinations
; begin Export Formats
Source: C:\WINDOWS\Crystal\u2f*.dll; DestDir: {pf32}\Seagate Software\SI\X86; Flags: sharedfile
Source: C:\WINDOWS\Crystal\u2f*.dll; DestDir: {win}\Crystal; Flags: sharedfile
Source: C:\WINDOWS\Crystal\crxf_*.dll; DestDir: {pf32}\Seagate Software\SI\X86; Flags: sharedfile
Source: C:\WINDOWS\Crystal\crxf_*.dll; DestDir: {win}\Crystal; Flags: sharedfile
; end Export Formats
; begin Page Ranged Export
Source: C:\Program Files (x86)\Seagate Software\Shared\ExportModeller.dll; DestDir: {pf32}\Seagate Software\Shared; Flags: sharedfile regserver
Source: C:\Program Files (x86)\Seagate Software\Shared\crtslv.dll; DestDir: {pf32}\Seagate Software\Shared; Flags: sharedfile regserver
Source: C:\Program Files (x86)\Common Files\Crystal Decisions\2.0\bin\ExportModeller.dll; DestDir: {pf32}\Common Files\Crystal Decisions\2.0\Bin; Flags: sharedfile regserver
Source: C:\Program Files (x86)\Common Files\Crystal Decisions\2.0\bin\crtslv.dll; DestDir: {pf32}\Common Files\Crystal Decisions\2.0\Bin; Flags: sharedfile regserver
; end Page Ranged Export
I'd appreciate feedback if this solves your problem.
