We have recently changed our application to save datawindow as .XLSX! rather than the old Excel! format which worked well in development, but causes app to crash when used by our testers. Both "PBDWExcel12Interop170.dll" and "Sybase.PowerBuilder.DataWindow.Excel12.dll" were copied to the runtime directory where the rest of the DLL's reside as instructed on the deployment help.
We don't install new versions of the PB runtime using the installer as we have around 500 users in various locations around Europe so and I now believe that the "Sybase.PowerBuilder.DataWindow.Excel12.dll" needs to be installed in the GAC. GacUtil.exe won't be installed on our user PC's and I believe that administrator rights are needed to do this!
Is there an established method to get around this or am misunderstanding what is required?
