[New-bugs-announce] [issue43983] Can't install Python v3.9.4 / 0x80070643 / windows 10 64bit

New submission from Marwan Essam <marwanes1818 at gmail.com>:

Hello, 
While I was trying to install Python version 3.9.4 on Windows 10 64bit, Error 0x80070643 - Fatal error during installation is showing, with a message saying " install the process cannot access the file because another process has locked a portion of the file", 

Note: There was an older version of Python installed on my laptop in 2018, but a while ago i did a system format, but some of the .XMl and .py files still there ( i don't know if that's the case)
