Dell Support Assistant Installation Error

The Support Assistant was being glitchy and buggy so I uninstalled it and try to reinstall it again and after it reached 100% it would give me a BSOD with Error:

PAGE FAULT IN NON PAGED AREA

So I left it for a few months like that. So today I checked the dell driver website to check if it was any driver issue so i scanned from website and installed a BIOS update. After that when I try to Install it then it shows:

Please help fix this issue as my laptop is shutting down when it wakes up from sleep mode so I need to scan for any issues...

Please respond Asap

Thanks
