Today I was been updating several Laptop and Support assist worked on one but not the other 3.

This was a great tool and I never had issues before.

Can you please supply a better update the reinstall, Software upgrade!!

I have uninstalled and reinstalled and it works the first time, but takes a long time to load up after a reboot and you only get one option - hardware check.

Not a happy customer.

Regards
