Software Deployment

Hello,

I need to edit Office documents by using Firefox APPV. (In Sharepoint)

I'm using Microsoft Application Virtualization Sequencer to do the APPV but i don't understand what i need to do so that firefox can see Office on the local computer.

Here is what i tried :

- Launch differents Office documents during the sequencer, and it creates link to office folder on "Package Files" tab

- Merge Office folder in "Package Files" tab.

- On "Advanced" tab, i tick :

- Allow all named objects to interact with the local system
- Allow all COM objects to interact with the local system
- Allow virtual application full write permissions to the virtual file

- Add manually link to each office exe in ProgramFiles.

- Modify registry and add this : 

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\AppV\Client\Compatibility]
"RegistryCompatibilityMode"=dword:00000001

No matter what i try, nothing happens, i always have "Could not start MS Office" error on Firefox when trying to update Excel file for example.

I found this :

https://docs.microsoft.com/en-us/microsoft-desktop-optimization-pack/appv-v5/running-a-locally-installed-application-inside-a-virtual-environment-with-virtualized-applications

But i think it's only if Office is another APPV and not local software.

I want to try this :

LOCAL_INTERACTION_ALLOWED=TRUE

But i don't understand where to write this in DeploymentConfig.xml and i haven't found any clue on it.

To resume :

I have Firefox 52 in APPV5 and Office 365 locally on computer and I need to see Office with Firefox.

Can anyone helps me on this topic ?

Thanks in advance.
