I recently had a question answered on how to fix the authentication type drop-down list on the Crystal Report Viewer logon page in Crystal Enterprise 8.0 ( http://www.experts-exchange.com/Databases/Crystal_Reports/Q_21165957.html
Having fixed this problem by copying the later version of the file Wcs_xn_reportviewer.dll to the C:\Program Files\Seagate Software\WCS\Components directory, I now find that some reports will not export to Excel from the viewer. I get the error message:
The export format 'U2FXLS:5' is not supported. [On Page Server: CRYSTAL.pageserver]
This is the problem I had as a result of applying Crystal Enterprise 8.0 Service Pack 1, which led to me reinstalling CE, which led to the logon page drop-down list problem, which I fixed, which led back to having the problem I started with - not being able to export some reports into Excel format.
I need to know how to fix this issue without reinstalling and re-creating the other problem I just fixed.
I have already spent a fair bit of time researching a solution to this one, but as noted ended up reinstalling as a last resort.
