I recently bought a new PC and the Dell SupportAssist program has continually failed to install. Firstly it tells me that it has encountered a problem and needs to restart, which I did several times, to no avail. I also attempted various fixes on these forums, without any luck. I called Dell and was told it wasn't something they could help with, because I bought it elsewhere, so I would have to speak to Curry's PCWorld. They got me to update the firmware, which didn't work, and then do a factory reset. Then the problem was just back to square one. Starting a virtual chat on the Dell website resulted in me uninstalling the program after stopping the services. Then installing the program via the Dell website download brings up the following message: Download failed. We were unable to download .NET framework/Core resource files. This may be due to a lost internet connection. Check your connection and try again." However, there is nothing wrong with my connection. Can someone help resolve this for me please?

The solution offered by Nathalia M doesn't work for me either - see https://www.dell.com/community/SupportAssist-for-PCs/Dell-Support-Assist-fails-to-install/m-p/8288015/highlight/true#M93938

If I choose the .msi file, it says "UI mode not supported."

Then it says:

"InstallShield Wizard Completed. The wizard was interrupted before Dell SupportAssist could be completely installed.

Your system has not been modified. To complete installation at another time, please run setup again.

Click Finish to exit the wizard."

If I choose the .msp file, the error message says "The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. Verify that the program to be updated exists on your computer and that you have the correct upgrade patch."
