[German]Can we run Microsoft Office as a click-to-run installation parallel to an MSI installation? Microsoft says no to this. But it seems that there is still a trick that works and bot packages may be installed in parallel.
What the problem?
Microsoft usually offers its Office suite as a click-to-run installation. A web installer then pulls all components of Office and sets them up on a target system. Only works as long as Microsoft offers the download.
However, there is also an Office Professional version for business environments, that can be installed via .msi files. The advantage: You have the installation files for the Office package on a DVD or on your hard disk and can install in one go, without downloading.
No coexistence – and some trouble
However, Microsoft does not allow/support a parallel installation of these two product variants. This causes some administrators to run into problems in business environments. Some admins told me, that Access or Visio and Project 2016 are only available as Click'n'Run via Microsoft Imagine. If a .msi install is used to distribute MS Office, standalone Click'n'Run packages can't be installed on those machines.
Parallel installation will work after all…
German blog reader Conny R. contacted me a couple of days before and drew my attention to a Technet forum post, that addresses this issue. Within the Technet forum thread Office 2016 (MSI installer) volume license incompatible with Visio/Project 2016 from MSDN (Click to run installer) a user wrote.
We have encountered a problem were we are unable to use both Office 2016 (MSI installer) and the latest versions of Project and Visio 2016 from MSDN.
Our academic institution has a Volume License agreement for Office and the installers we are provided are MSI based. Our department has a Dreamspark subscription which allows us to install Project and Visio 2016 on computers for non-commercial research and teaching purposes from MSDN. The problem is that we are unable to install both pieces of software in lab computers because MSI installer and Click to Run installer cannot coexists on the same machine.
The scenario, some administrators pointed out to me. Within the above Technet thread, user thenicnic posted a workaround.
I discovered a workaround while I was wondering how the C2R installer checks if there is Microsoft Office 2016 already installed on the PC. The assumption was that it just asks the "list of installed programms" in the registry (it's the one you can also see via control panel). I googled for a way to hide Office from this list and found this manual: http://woshub.com/how-to-hide-installed-programs-from-programs-and-features/
It actually works this way:
- Go to the registry path HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\
Windows\CurrentVersion\Uninstall\Office16.PROPLUS (x86 Office) or HKEY_CURRENT_USER\Software\Microsoft\Windows\
CurrentVersion\Uninstall\Office16.PROPLUS (x64 Office)
- Add a DWORD value called SystemComponent and set it to 1
- Now make sure that in the control panel (Programs and Features) Office 2016 is absent
- You can install Visio 2016 now with the C2R installer, after that start it and enter your serial
- Remove the registry value from step 2 so that the Office 2016 entry appears again
Hope this works for you
I can't test it here – but perhaps this is quite interesting for administrators in the academic environment of universities. You could give feedback whether this works and is useful or not.
