Solved: Multiple version OneAPI Installs

andrew_4619 · ‎04-30-2023

Looking in VS2022 tools/options and also in windows settings I have 5 versions of the base and HPC toolkits installed which is quite a lot of disk space. Is uninstalling some of the older versions (oldest first order) likely to cause problems? What is the recommended procedure?

Thanks, Andrew

Well to answer my own question I just bit the bullet and used the Intel Uninstaller to remove HPC/Oneapi toolkits starting with the oldest. I removed three of the 5 versions and recovered about 100GB of disk space. I am pleased to note that VS /IFort still works OK. One slight confusion is that whichever version you uninstall you get the same uninstaller which shows the latest version but this in fact has a dropdown combo box that allows other (older) versions installed to be picked and 'modified' one option of modify being 'uninstall'.
