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.

Here is the list of support files I use in my accounting software package regarding Crystal Reports exporting. It is a segment of an Inno-Setup script, but you should be able to get the idea from this list of what to look for:
; 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
