I could not find a forum specific to the Intel Software Manager (please feel free to direct me elsewhere if necessary). I recently migrated my C++ compiler tools from 2018 to 2019 - having removed all older versions of the studio. However, ISM keeps trying to notify me that an update to 2018 is available. I'm not sure if it's polling some registry key left behind by the uninstaller and thinking the product is still present or if it is keying off some file(s) that didn't get deleted, but it's annoying to continually get a popup notification for an update that is not applicable.
If there's an easy solution to this problem, please advise, or perhaps you can forward this report to your ISM team for resolution.
