Error installing spacedesk  

Hi @jimii,
Is your secondary machine's operating system, Windows 10?
What is the build version?
You can check it by running "winver".

Yes, the secondary machine is Windows 10, version 20H2.

Hi @jimii,

Can you try again?

We just checked here on our side and it seems fine, we can download and install the app from the Windows store properly.

If you still have the same issue, can you try to download any app from the store to check if it will download and install properly?

The same problems happens with other apps. What could I do?

Hi @jimii,
thanks for confirmation.
Can you try the following:
- run Command Prompt as Administrator
- type the commands:
reg ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\current\device\Accounts" /v AllowMicrosoftAccountSignInAssistant /t REG_DWORD /d 1 /f <enter>
sc config wlidsvc start= demand <enter>
