Programmatically change Crystal's working folder (C:\Windows\Temp) to another in order to prevent having to set permissions on C:\Windows\Temp

We are using the CrystalDecisions.CrystalReports.Engine.ReportDocument in Crystal Reports 2008 SP2 to run reports.

Is there a way to change the Crystal scratch pad folder from C:\Windows\Temp so I do not have to grant users rights to C:\Windows\Temp?

I looked at this discussion:

but the solution for that person was to modify permissions to have access to the C:\Windows\Temp folder.

We do not want to modify permissions on this system folder. We would like our program to create the temporary work file in a non-system folder (that we specify) vs. the C:\Windows\Temp folder when building a report, and then we can grant the proper permissions to this non-system folder.

Is there anyway to do this?

Thank you.

    The location of the temp folder (for CR temp file generation) is set in windows environment variable %TEMP%.

    Whatever location is set for %TEMP% variable in windows environment variables, CR temp files get generated there.

    Changing the Windows Environment variable path is out of the scope of the CR SDKs.

    So, No. there are no APIs to change the location for CR temp file generation.

    However, see if you could develop your custom logic in .NET to change the path of the %TEMP variable.
