SA, cannot run the application, Inspiron G3 17-3779

Question

Hi,

when you try to start SupportAssist, the blue application dialog appears for a while and disappears immediately. Therefore, the application cannot be started. In the Windows log there is the following error:

Faulting Application Name: SupportAssistClientUI.exe, Version: 1.0.0.0, Timestamp: 0x5cac35d4
Faulting module name: twinapi.appcore.dll, version: 10.0.17763.292, timestamp: 0x270a22eb

Message ID: b0e7f021-e3de-49f4-8de0-f6c047224562 \ t
The full name of the failed package: DellInc.DellSupportAssistforPCs_3.2.4.0_x64__htrsf667h5kn2
Application ID related to the failed package: App

Does anyone know what the problem might be? I have uninstalled and reinstalled several time.
Thanks for the reaction.

Can you check if the following error is in the event logs? If so this is a known MS defect and you could try the workaround in this thread

The following error messages can be found in event log for this issue (Event Viewer > Applications and Services Logs > Microsoft > Windows > Apps > Microsoft-Windows-TWinUI/Operational):

Activation for DellInc.DellSupportAssistforPCs_htrsf667h5kn2! App failed. Error code: Access is denied... Activation phase: COM ActivateExtension.
Activation for DellInc.DellSupportAssistforPCs_htrsf667h5kn2! App failed. Error code: This app does not support the contract specified or is not installed... Activation phase: No phase defined.

If the above error exists or not, you should be able to launch via the command window and create your own short cut. Possible workaround could be to upgrade the OS.

Workaround to launch.

Open a Command Prompt (Admin), and type:

1) cd\

2) cd C:\Program Files\Dell\SupportAssistAgent\bin

3) SupportAssistUI.exe Launch

ISSUE

This issue has been observed when the Windows registry gets corrupted (possibly due to multiple installation/uninstallations, among other potential reasons) and has been identified as a Microsoft defect that appears when the OS is upgraded from RS3 to RS4. The issue appears to stem from a defect where the normal Microsoft process for managing Registry cleanup procedures fails to uninstall the appx installation packages from the system upon completion.

Hi, this error message appears in Event Viewer. I tried to run SupportAssis according to the listed workaround. The application starts - loading, but then the following appears: The page is unavailable • Check that the URL http: // localhost: 57385 is correct • Search this site in Bing • Refresh the page There is nothing to click or manipulate. The windows can only be closed. I started CMD as administrator.
