We are upgrading CA Asset Portfolio Management to C4 and upgrading CA Software Asset Manager to 4.2.2.
When we run the SAMImportExport.exe on the SAM server, it errors with: The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program.
The SAMImportExport.exe is a patch upgrade, not a full install. The SAM server did not have a prior version of the SamImportExport service installed.
Install the SAMImportExport service from the original APM 12.9 DVD media. The .msi installer for this service is in the \SAMImportExport directory of the APM 12.9 DVD media.
