I am looking for assistance deploying Zimbra Outlook Connector using GPO.
1.) When installing using MSI from GPO it fails with following error.
> Calling the Windows Installer to install application APP from policy ZCL. The install of application APP from policy ZCL failed. The error was : %1605

Error description --->
ERROR_UNKNOWN_PRODUCT 1605 This action is only valid for products that are currently installed.

If you run the same MSI locally using msiexec /i ZimbraConnectorOLK_8.0.0.673_x86.msi /quiet
it installs fine without any errors.

Any idea why would GPO installation fail with 1605?

2.) The MSI comes up as having Arabic Language. I know some people suggested going to MSI with orca and deleting everything except 1033 from Language field - but I did that and it still seems to be coming up as arabic for some strange reason. Any idea how that can be fixed?

Thank you for your help.
