Deploying DUA 2.x through GPO and getting error: "Error reading registry data, installation corrupted" (4368797)

A common reason for this error is an incorrectly configured deployment package, specifically:

• Missing MST transform file required for proper installation.

DUA 2.x requires an MST transform file to be deployed alongside the main MSI package when using GPO.
This process is documented in the DUA User Guide:  Desktop Update Agent User Guide

Manual Installation Test

To confirm the issue, try installing the MSI with the MST file manually using this command:

msiexec /I "<DUA_MSI_file>" TRANSFORMS="<DUA_MST_file>"

• Replace <DUA_MSI_file> and <DUA_MST_file> with the actual file names or full paths.
• If this succeeds, the error is due to the missing MST file in the GPO deployment.
