When I try to use a PC I bought as reserve, I cannot get Windows installed with mye Microsoft account ******@isaksen.com because it says that "That Microsoft account doesn't exist". When trying another account, it states that it sends info to Authenticator, but Authenticator receives nothing despite Authenticator working perfectly in other cases. When I try alternative SMS, it says something like "this service is not available at this time". So i very much need the Autodesk Inventor to work on either or both PCs NOW, but neither PC will help. It started with this PC I am writing on, where Windows Explorer did not work normally, but my IT Service provider managed to fix that after some expensive hours. They were unable to fix the Inventor/AutoCAD issue, despite using several hours on this.
When trying assistance in my account, that does not work, not via Teams either.
Office says that my PC is Windows 10, but it really is 11.
There seems to be something seriously wrong with my account.
HEEEELP!
