Azure Sphere will not uninstall nor upgrade

Question

Platform: Windows 10

AzureSDK: 20.7.0.18252

The only real answer i have found is to delete all AzureDSK entries from Registry and Delete the directory for Azure SDK - Is that still the accepted method when AzureSDK does to work nor unstill/update to a new version?

Are there any recommendations - Thank you.

Accepted Answer

Unless there is a better, less blunt force answer this worked:

1) download and use Revo to uninstall the Azure Sphere SDK

2) using Registry Edit and delete the following

 Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Azure Sphere:  

 This contains Sysroots and Tap Driver Install sub directories

you do not have to find every instance to get it to work, not sure of the long term impacts of this forced method.

Hello @Roger Mahler - We are sorry that you are having a below par experience using Azure Sphere product.

If you are still experiencing the issue, can you please try disabling the AzureSphereDeviceCommunicationService by running below command from an elevated cmd prompt?

Also, did you try uninstalling the TapDrivers and attempting to uninstall the SDK software?

Thank you for using Azure Sphere and appreciate you sharing the feedback.

Answer

seems like when i get a new update from microsoft - i am on the early release program i loose the TAP - found the correct part of the docs to solve it:

https://zcusa.951200.xyz/en-us/azure-sphere/install/troubleshoot-installation

Check the TAP-Windows adapter configuration

Delete the TAP in the device manager and run the following

powershell -ExecutionPolicy RemoteSigned -File "%ProgramData%\Microsoft\Azure Sphere\TapDriverInstaller\TapDriverInstaller.ps1" Install

one step closer, thank you.
