you'll need a new app to open this windowsdefender" error on server 2019
I still have this problem , tried all solutions suggested in post of TomW42 dated Jan,14th, 2019
any other idea ?
Hi Patrick, sorry for late reply.
I have this situation in the server from a few months,
No way to access Win Defender , every time I try I get the same answer .
First I tried the solution suggested in the mentioned post : (power shell command) Add-AppxPackage -Register -DisableDevelopmentMode "C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy\AppXManifest.xml"
but no result.
Later I tried to uninstalling Defender and reinstalling it (using power shell commands) but during uninstalling I received an error message and nothing changed .
Any suggestions ?
