Ah, I think I understand Friedrich,
So adding my product version number to the uninstaller, and log file
should enable me to select a particular version to uninstall:
%_SB_INSTALLDIR%\Uninst_[PRODUCTNAME]_[PRODUCTVER].exe
%_SB_INSTALLDIR%\Uninst_[PRODUCTNAME]_[PRODUCTVER].log
Previously I just had [PRODUCTNAME].exe and [PRODUCTNAME].log
Thank you.
Regards,
Neil.
