3rd party patch management trying to install 32-bit version on 64-bit Windows

Attempting to run 3rd party patch management to upgrade to PDF-XChange Editor, I get the error:

Operation probably not completed for PDF-XChange Editor(8.0.339.0). ExitCode: 1603

When I check the Windows event logs on the device, I see:

The device is running Windows 10 Pro 1909 x64, and this is correctly listed in the device summary.
