Hello! The laptop came with this OS and it worked fine until about 2 weeks ago when I started having problems uninstalling software. Until then, it worked beautifully.

Uninstall all Windows updates, starting from the newest and working backward, until you have uninstalled all updates which cover the time period that this problem has existed. Reboot and try the install again.

I uninstalled the ones that I was allowed to uninstall. Some of them did not have the option to uninistall. I then attempted to reinstall TurboTax 2017 or uninstall a program. I still get the 2502 error code.

You might be able to uninstall them when you are in Safe Mode.

I was unable to uninstall the Microsoft .NET Framework updates.

The error message code was 0x80070643 "fatal error during installation"

I tried uninstalling in Safe Mode as well.
