Hoping someone can point me in the right direction here.
I'm running into some issues deploying both Office 365 ProPlus (Monthly) and Project 2019 Volume Licensed to workstations. Independently, each software package installs without error, but when I install ProPlus, THEN Project 2019, I get a "Blocking Application: Microsoft Office 365 ProPlus en-us" fatal error.
Reading https://docs.microsoft.com/en-us/deployoffice/install-different-office-visio-and-project-versions-on-the-same-computer, I find that I should be able to do this, since this is a supported scenario. Office 365 Monthly is at version 1809, which is greater than the first version recognized at 2019 (version 1808).
However, I run into this additional note: "For Office 365 and Office 2019 products, all products installed on the computer must be using the same update channel". From https://docs.microsoft.com/en-us/deployoffice/office2019/update#update-channel-for-office-2019, I read "“PerpetualVL2019” is the only supported update channel for Office Professional Plus 2019 and Office Standard 2019. It's also the default update channel for volume licensed versions of Project 2019 and Visio 2019"
If I change the deployment channel for Project to "Monthly" (from PerpetualVL2019), isn't this just the same as if I were using "Project Online Professional" (the Office 365 flavour of Project), and not volume licensed? This scenario allows the software to be installed, but I'm not sure where it's at license-wise.
Any help, direction, current experience with deploying Office 365 ProPlus and some Volume Licensed 2019 components is appreciated.
