Hi Janzzo, I think that there is a problem with the system of yours. Kindly run this command, just copy-paste it into an elevated Command Prompt(Click on the start menu, type cmd, a app with name cmd or command prompt will come up, right click on it, click on Run As Administrator, a windows will pop-up click YES, if a window does not pop-up let it be, see if command prompt opens, if not then try again) Now type this command-
sfc /scannow
This process will take a bit of time. Let it do its thing, NOTE- Please don't use your PC while the command is running, it may not work properly if you do so.
Do this and report.
Regards,
