GPO is applied but software is not installed

deploymentgroup-policymsi

I'm trying to install Zimbra Connector for Outlook via Windows Group Policy on target computers. The problem is the policy is applied to the computers but software is not installed. I've checked the following:

  • GPRESULT /R shows that the policy is applied to computer but the software is not installed.

  • When I use another msi installer file (other then Zimbra Connector) it is installed as expected via the same GPO.

    • I'm able to install Zimbra Connector silently as user, that is: msiexec /i \\path\installer.msi /quiet

DC: SBS 2008

test computers: Win10 Pro x64, Win7 Pro x64.

edit:

I've enabled application management debug logging which gives me the error: %1605

I've also turned on Windows Installer verbose logging but it doesn't create a log file.

Check RSOP.msc at the client workstation, it should provide further information.

Does the computer account have access to the share where the installer is stored? Are there any event log entries from the Windows Installer service that would indicate the installer process failed?

Have you customised the Zimbra Connector installer as per their docs? https://zimbra.github.io/zco-docs/8.8.8/ZCS_Connector_For_Outlook_Admin_Guide.pdf (older guide https://www.zimbra.com/docs/ne/5.0.19/zcs_connector_for_outlook_guide/)
