Error installing MSI (from microsoft) Error 1721. There is a problem with this Windows Installer package.

Surface Book 2 13" Latest version of windows, should be fully patched. (1903)

I have tried installing the new surface dock update app but i keep getting an error. I have tried restarting installer service, as well as the MS Install/Uninstall digicab - that doesn't list the 2 programs i am getting an error with. I have also run surface diagnostics but any repairs made have not affected anything. 

Product: Surface Dock FW Update 1.42.139 Update 19.084.31680 (64 bit) -- Error 1721. There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor. Action: InstallDriversPnP, location: C:\Program Files\SurfaceUpdate\, command: powershell -executionpolicy unrestricted -NoProfile -NonInteractive -Window Hidden -Command "& {Get-ChildItem -Recurse -Include *.inf | ForEach-Object {pnputil -i -a $_}}" 

I then tried installing the Surface Book 2 update bundle, and I get the same error:

As mentioned above i am getting the same error trying to install 2 different MSI files distributed by Microsoft. One is the latest surface dock updater msi, the other is for latest surface book 2 deiver pack msi. 

I don't understand what you are asking me. 

I can't install either msi file. 

See if this helps.

I tried that - mentioned in first post. It doesn't list these apps i am having a problem with even though event log and temp logs are recorded with errors. 

Have you tried sfc /scannow ?

I'm not sure if you should be running 1903 in a 13" Surface Book. I's a definite no for the 15".

If you're up for it you might want to do a full Reset.

I am taking updates straight from MS. This is a Surface Book 2, but yes reset may be next if no other ideas.

Yes, i i mentied trying the first 2 above, and i even tried the third; though compatability mode for a windows 10 only app on windows 10 didnt offer any logical hope. 

I did search before posting.  

are you running Avast or another third party AV?

No. Standard MS stuff.
