Unable to upgrade HPC Toolkit from v2021.3 to v2023.2

[dfrickmann]

I am trying to upgrade the Base Kit (Math Kernel Library) and HPC Kit (Fortran Compiler) from v.2021.3 to v.2023.2 on Windows 11. 

I read somewhere that it was recommended to first remove the installation of the old toolkit, so it attempted that. I was successfully able to remove the Base Kit, using the Software Installer GUI. However, when using it for the HPC kit, it crashed, and I was completely unable to remove the toolkit. 

I tried to repair the installation, but that also failed, and no matter what I did, I was unable to uninstall the toolkit. Finally, I resolved to manually remove it, by removing the entire oneAPI folder from `Program Files (x86)`, and the cache from ProgramData. After rebooting I attempted to install v2023.2 of the two toolkits. Once again, the base kit was installed successfully, but the HPC kit failed. 

I have attached some log-files suggested by the Software Installer, and I would like some recommendations to get the HPC toolkit installed, without having to wipe my machine. 

Thanks in advance

Why not just update to the latest, there is little code that will not work with the new compilers and you will save a world of hurt.  

Old is old for a reason.

Hi John,

v2023.2 seems to be the latest version with a Fortran compiler, that also supports macOS. Since I am also upgrading Linux and macOS systems, it made sense to perform this upgrade at the moment.  However, the uninstallation of v2021.3 seems to only be an issue on Windows.

I want to leave this here for completeness. I've uninstalled the v2021.3 version and installed the v2023.2 version on a bunch of systems now. Windows is the only OS in which I sometimes have to perform manual uninstalls, due to the Software Installer failing to perform the uninstall. 

By following these steps, I get a proper manual uninstallation:

1. Manually remove the oneAPI folder from C:\Program Files (x86)\Intel.
2. Remove the cache directories from C:\ProgramData\Intel.
3. Also remove all mentions of oneAPI, and in this case 2021.3, from the Windows Registry.
4. Launch the Visual Studio Installer, and uninstall Visual Studio
5. Reboot the machine
6. Reinstall Visual Studio.

After performing those steps, I can run the oneAPI Base kit and HPC kit installers without issues.
