Ron,

The solution that worked for me was,

Downloaded and ran Revo Uninstall to uninstall SupportAssist.

Then followed the following from Dell care:-

Ensured the following folders had been deleted, or delete them

C:/ Program Data / PCDR

C:/ Program Data/Supportassist

C:/ Program Data/ Dell/Dell data vault

C:/ Program Files/Dell/Supportassist

C: Program Files/Dell/Dell data vault

C:/ windows/Temp (everything inside the folder) However I found that a number of items would not delete, so moved on.

Open Edit Registry,

Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services Key

Delete Dell hardware service,Delete Dell client management service, delete Dell updates.

open device manager > system devices: you will see 2 Dell data vault devices, uninstall the second one (bottom one)

Reboot

Install SupportAssist

SupportAssist then installed and could be run.
