Managed or restricted environments

If you're not able to install applications on your computer, your administrator or IT team may need to do this for you. 

Send them a link to Administering the Atlassian Companion App for information about MSI installation. 


Companion is installed twice in Windows

It's possible to have two versions of Companion installed simultaneously if you have installed Companion using the installer (.exe) and the MSI (.msi).  If this happens, you should uninstall both versions from Add/Remove programs and then re-install Companion (either using the .exe or the .msi depending on how you want to be able to update Companion in future).  

Remove residual files after uninstalling Companion in Windows

If you need to completley uninstall Companion you may want to check if any residual files remain. 

Where does Companion save files in Windows?

The default installation directories are:

  • EXE: %LOCALAPPDATA%/atlassian-desktop-companion
  • MSI: Program Files (x86)/Atlassian Companion

The app stores temporary data and edited files in:

  • %APPDATA%/Atlassian Companion
  • C:\Users\<UserName>\.atlassian-companion

Companion creates the following registry entries:

  • Computer\HKEY_CLASSES_ROOT\atlassian-companion
  • Computer\HKEY_CURRENT_USER\Software\Classes\atlassian-companion
  • Computer\HKEY_CURRENT_USER\Software\Microsoft\atlassian-desktop-companion

You can do a registry search for "atlassian" to locate them. These are used for both the MSI and EXE.
