Windows has a habit of making life difficult for AMP by ignoring its requests to not cache certain AMP components, meaning that things can often get a little rocky after an update.
If this happens to you - go through the following steps:
Follow these steps in the exact order given, do not skip any steps,
- Stop AMP fully by running
ampinstmgr stopall
in a new command prompt. - Use Task Manager to make sure all AMP.exe and AMPService.exe processes are stopped.
- Download a fresh copy of AMPSetup.msi - and run it in Repair mode.
- Run
ampinstmgr --nocache upgradeall
in a command prompt. - Reboot the system
After this, everything should be working fine.
