Windows co_release 21376.1 will not install

After downloading the released version of Parallels, I was checking my Windows on ARM to see if it still worked before buying a license.
Windows 21376.1 install failed with 0xc1900101.
I tried resetting Windows and got the same result

 

I have the same issue. Glad I am not the only one. I had the issue with a previous build, and it fixed itself after a while.

 

Me too. Same error.

 

and same here trying since release but still fails. - will wait patiently

 

Try disabling Shared profile in VM configuration / Sharing, then running Windows Update.
If that does not help, also try to uninstall and reinstall Parallels Tools.

 

I reinstalled Parallels Tools when I reset my windows install.
The update worked today without any action required.

 

Mine worked and did not have to worry about tools. Not sure why.

 

FYI Stanislav, it wasn't necessary to disable Sharing, or even restart the Mac.
The problem resolved it self spontaneously.

 

Same here. it fixed itself.
