When opening SA today I was greeted with an update prompt. I went along with the update, however, it went no further than "downloading and starting up files", at which point the percentage bar went up to 100%, then gave me the error: "Installation failed - We were unable to complete the installation. Please reboot your PC and try again".

I rebooted my PC and tried to update the application twice to no avail. I then tried to uninstall and reinstall SA, and the installer had the same issue - it gave me the same error message as the one that the application gave. 

I tried following this solution posted by @XPS_Man, which included deleting some dell files and registry keys, to no use, unfortunately.

Has anyone else encountered a similar issue or perhaps a possible solution?

All help is appreciated.
