@hknet said in Notepad++ release 8.9.3:
as usual with a lots of other MSIs we take to the softwareinstallation in the GPO editor, then select “new - package”, select the current npp.8.9.3.Installer.x64.msi file from our GPO deployment path, open it, then select to deploy the package in a customized version (German: Erweitert), but tried all three options in the meantime, all end with the GPO editor reporting that adding the package to the GPO went wrong because the deploymentinformation can not be read (from the package) and we should check if we got the correct softwarepackage…
It’s likely that Windows has placed a “Zone.Identifier” alternate data stream on it, marking it as untrusted.
If not, please check the network share where npp.8.9.3.Installer.x64.msi is stored has Read permissions for both “Domain Computers” and “Authenticated Users” (or at least your specific admin account).
