Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi geoff,
Thank you for the reply.
First, please accept my apology for not being able to find any official documentation or third-party article about command line switches for you.
And I agree with you that "It looks like the switches are similar to what is in the xml configuration file", and there are different methods to change the specifications or deploying methods, but the result is same by going through any process.
Since, you want to switch the Office apps from 32 Bit to 64 Bit, I recommend you go with Office Deployment Tool. In addition, you can also give the feedback to related developing team about the article on command switches in Office 365UserVoice.
Best regards,
Jazlyn
