Caramel4406,

Did you get support assist installed?

What I did in detail:

Uninstall current version and reboot your pc. Make sure that windows is up to date (version 1903),  that you have the Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 1903, Then download supportAssist installer from here: SupportAssistInstaller.exe 

Right click the downloaded file and select "Run as Administrator". Let it do its thing and be patient. Hopefully it will work for you also. I manage do install supportassist successfully on my two laptops (Xps 15 and Alienware 17 R3) by following these steps. The important factors seems to be that windows is up to date and that you run the file as admin.  

Uninstalled everything support assist related on my XPS 9570 (with latest updates of Windows 1903), then tried to install using admin with the method above, still no joy for me.

Support assist installer loads, downloads one set of data, then downloads a another set of data, then just appears to hang, no error or feedback

Make sure that you have the Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 1903.

It may take several attempts. Just close the installer with the X and try again. When it worked for me, the second downloading process took longer.

Tried my method on 3 different systems and all was successful. Sorry to hear that it didn't work for you. 

Seems to be very random if it works or not.

DELL-JesseL,

Sorry for my late reply.  I had abandoned for a couple of days.  But after the latest Windows update, SupportAssist is up and running.

ThomasAAT,

YES!!!!   It works!!!  After the latest Windows 10 and NET framework updates, SupportAssist is up and running.

I don't know how many hours I spent on that software.

Great to hear! I have been running SA problemfree since it installed. 

ThomasAAT,

SA is there and running, but when I press "history", it says there is an error and cannot start,  Is history working for you?

I tried to restart the computer, but the error is still there.

I know that I could remove SA and reinstall, but I'm afraid it won't work anymore...

Thanks

Yes, my history is working as normal:

You can try to uninstall it and install it again. Make sure to run CClaner and fix registry errors and temp files before installing as admin again. 

Just as I replied I checked SA for new updates and there is. Download det new file and run as admin before trying to uninstall your current version.
