Supportassist give unexpected error

Update: I ran "Run all" tonight after installing version 2.2.3.2 on my Windows 7 Home XPS laptop this morning and each scan was successfully completed, including the Hardware Scan.

Same error, added 8GB RAM (now 16GB) a few months ago, XPS 8700 runs great, but SupportAssist cannot complete hardware scan.  Where is Dell on this?

Same issue on my Inspiron 7510 with 64 gigs of ram. Running the latest version of SupportAssist. Has not run anything but the hardware and drivers update since July 10. Very annoying, Dell!

Finally, I managed to solve it, at least in my case. Dell Inspiron  7547 with Windows 10 Home edition. 

I uninstalled Support Assist and then downloaded the file again from Dell site and installed it. After login in again I tried the Diagnostics again and this time the Hardware Test was successfully completed after a month, not being able to make it work.  I don't know if this was the solution or coincidentally it was a system update yesterday after I did the before mentioned process.

Now I could run all the troubleshooting Hardware test with no problem.

I did the same thing with success now. I uninstalled Dell SupportAssist using the Uninstall Apps feature in Windows  10 Settings ( I did not do anything additional to clean leftover registry keys), and downloaded and installed the current version of Dell SupportAssist (2.2.3.2). Run All ran all  5 PC optimization tools successfully this time. It did take a long time (>15 minutes) to complete the Scan Hardware section, but eventually finished it. It appears to hang at the Advanced Pattern Test, and was stuck at 98% completion for the longest time, but eventually finished it, so be patient. This new version of SupportAssist does appear to work now. Thank you Dell.

Every time this happens, I have to uninstalled and then reinstalled in order to run the full PC scan again without any issue.

I remember this did not happen in the previous version (Not even once).

Ever since I've upgraded to the latest version of this Dell Support Assist (ver 2.2.3.2), this seems to be the norm. I hope Dell can seriously look into it on whether there are bugs in the latest version. Especially for the Hardware Scan.

I spoke too soon , Bohuatoh. I thought the problem was fixed with an uninstall/reinstall of Dell Support Assist for PCs, but it is not. It ran one time after the reinstall (Version 2.2.3.2), but like you, it again hangs on the Scan Hardware - at 98% on the Advanced Pattern Test. The other 4 items will run individually, but "Run All" will stop at the Advanced Pattern Test in Scan Hardware. I miss being able to run these tests as my PC did perform better when I was able to do so. I too wish that Dell would address and correct this issue.

I had a similar problem today.  Not just PC's app (I have a 5759 laptop) but also when connected to the website - hung up when attempting to do a hardware check.  I'm glad to say that I re-installed the App and all is OK now (as far as one can tell).  To  the gents and ladies at Dell - note that the hang up occurred with both on line and the app trying to do the  hardware check.  Food for thought?  Regards

This isn't a Microsoft problem.  It is a Dell problem.

I have the same problem. It hangs at 0%.

Hi there, Thanks for your post. How did you make sure that all previous registry keys were removed? 

Hello Dell:

There is good news and bad news with the release of your new version (3.0.1.62) of SupportAssist. The good news is that the Hardware Scan now runs completely (although it still required almost 5 minutes to do the Pattern Scan portion of the test). The bad news is that the Clean Files test does not run at all now. It hangs at "Preparing for Clean Files..." at 0% completion, and generates the "An Unexpected Error Occurred in SupportAssist " message. I do not think your work on SupportAssist is done just yet. Is anyone else is the Community experiencing this problem with the new release of Support Assist, or does anyone have any suggestions to fix it?

Same issue, but the hardware scan for me.  I get the unexpected error when it starts the Scan Hardware.  I close it, reopen, and can run the other tests.  This is brand new Inspirion 3470 with nothing even on it yet, still doing setup and updates.  And here I got a Windows box after 4 years of being strictly Mac only.  

Dittoh! I am facing the same problem last week. I don't know what to do now and I am stuck now. Give me an instant solution. 

Thanks
