Intune Uninstall Error

[JoshB531]

Hoping someone can help me with this issue?

I am having an issue uninstalling a Win32 app deployed from Intune. The installation works fine but whenever I try and un-install from Company portal I get an error saying uninstall failed. 

I believe the .msi uninstall command in Intune is correct and it works fine if I run in command prompt as admin. The detection rules are right as its updating the installation install status in Intune. 

Looking through the Intune logs, I keep getting this when I try to run uninstall 

"GetRegistryValue encountered an exception: System.NullReferenceException: Object reference not set to an instance of an object.at Microsoft.Management.Services.IntuneWindowsAgent.AgentCommon.RegistryHelper.GetRegistryValue(String key, String valueName, String defaultValue, Boolean check32BitOn64)"

The application was a msi and packed up as a intunewin file. 

Any help would be great

Could you share your settings for the Intune package? What's your detection?

Sure, here is the setup:

The last " in the uninstall command shouldn't be there

[#5]

@Harm_Veenstra 

Thanks, I will try removing and report back.

So I try removing the extra " in the uninstall command but still failing.

The latest logs show this.

Just another question... Why did you package the .MSI file? Is it just the .MSI file, or are more files in the installation folder? You could alternatively add the .MSI file to Intune as a Line-of-business app. The install/uninstall/detection is based on MSI technology and is done automatically.

-Edit-

Never mind, you want to have users to be able to uninstall it themselves.

[#8]

Could you add this to the uninstall string and check the log?

/l*v "c:\windows\temp\uninstall.log"

@Harm_Veenstra 

Yeah it’s just a .msi file with no other files.

i was under impression it was best practise to deploy as a Win32 app rather than using a line or business app. I am fairly new to the packaging game in intune.

Are there any negatives to using a line of business app. I really need to the ability to remove this app both from company portal and from the remove app section in Intune admin 

[#10]

Thanks will try that. Do you add that to the end of the uninstall command?

[#11]

Yes, after the /qn with a space in between.

[#12]

Any update?

[#13]

Sorry for slow reply, No I am still facing the same problem. I even tried as a line of business app.

I have a PowerShell script which kills the app and removes perfect. If I package that up with the .msi as a intune.wim file. Can someone confirm what I should put as the uninstall command on Intune.

Thanks

[#14]

powershell.exe -executionpolicy bypass -file .\nameofpowershellscript.ps1

[#15]

Thank you, I think I tried this already but I will try again today.

Could you also confirm, if you have a .cmd file to trigger the install, what do you type in the install command on intune? Can you just type filename.cmd or do you have to type something before it?

Thanks

[#16]

Just filename.cmd is sufficient

[#17]

Any update?

This has now been resolved. I found out late Friday that our new VPN client was blocking PowerShell and cmd scripts from Intune.

Thank you for all your help.

@JoshB531 Ah! Didn't expect that. Good find, and I'm happy that it's resolved!
