Two versions of Atlassian Companion showing installed, uninstalls failed Edited

Presently my system has two versions of the Atlassian Companion application installed. One appears to have been an MSI install (this one seems to have uninstalled but left remnants behind/unclean uninstall) and the standard EXE. 

Is there a clean way to completely remove all of Atlassian Companion and its residual files?

Both MSI and EXE store temporary data in:

%APPDATA%/Atlassian Companion

and the edited files in:



Companion also creates the following registry entries:


 You can do a registry search for "atlassian" to locate them. However please note that these are used for both the MSI and EXE.
