We haven’t tested this particular file, but for .MSP file deployment, in general, if you use the BatchPatch ‘Deploy’ option, you’ll be able to select the .MSP file in that form window, and then BatchPatch will automatically provide the correct syntax, which you’ll see in the “Command to execute:” field as follows below. This means that you will not have to add any of your own syntax. Just select the .MSP file to deploy, and use the built-in syntax that BatchPatch autofills for you:
msiexec.exe /p "FoxitPDFEditor202521_L10N_Setup_x64.msp" /q
or if you also select the “norestart” option in the BatchPatch Deployment configuration window, then it will look like this instead:
msiexec.exe /p "FoxitPDFEditor202521_L10N_Setup_x64.msp" /q /norestart
==============================
However, at the bottom of the page you linked, they provide some different syntax options as compared to what I showed you above that BatchPatch will autofill. So, if you run into problems where the BatchPatch built-in syntax does not work as expected, then try the alternate syntax that is provided by Foxit on that page. It’s their installation package, so presumably they should know.
