Trying to install Win11, defeated by VirtualBox

The OP shows a VirtualBox installation error message indicating a failed upgrade of VirtualBox from Version 6.1.22 to 7.0.20. It appears if the named msi file, required to uninstall an old version, has 'gone missing' from the temp folder it should be retained in.

The answer is to download the old 6.1.22 Installer from VirtualBox Old Builds and extract the required msi file from the installer; then place it where it's expected to be and then re-run the 7.0.20 installer/upgrade.

Vmware offers more, seems more advanced, more polished.

However, I've seen Vmware take down the Host OS so many times, when VMs are really taxing, I prefer VB.

For the record, we are talking fairly muscular home PCs, with dual Xeon 14 cores, and 256gb of memory, running Ubuntu Server, and having numerous SSDs.

In the end, I went from using VMs on Ubuntu Server, to running pile of containers on Fedora Server, far more efficient use of resources.

By simply deleting that VirtualBox version on my system Win11 installed, no problems.

It seems to me that can be explained in different ways and would not help others if they have the same problem.

What did you really do?
1. Uninstalling the VirtualBox version by using some unstalling program? If yes, which program?
2. Deleting this folder: C:\Program Files\Oracle\VirtualBox or any other folder that has the VirtualBox program in it?
3. Something else?
