and I got the errors described previously (see the screenshot) as soon as it opened Run the command: md `cd D:\Unknown\Users\Administrator\AppData\Local\Temp`
Since I wasn't able to uninstall it normally because the path wasn't on C:, I deleted the folder 'Virtual Box' with all the files, but I got the same errors I tried to reinstall it but I get some error messages telling me that I need to choose a different path and that I cannot uninstall the previous version. Today I did the downgrade to Windows 7 again and I can't open VirtualBox anymore because I get this error: Failed to create COM objectĬallee RC: REGDB_E_CLASSNOTREG” (0x80040154) VirtualBox did work properly with both versions of Windows and I was able to run everything perfectly.
I installed Virtual Box on Windows 7 Ultimate 圆4 and then I upgraded my system to Windows 10.
