Since upgrading to version 8.4 I hve noticed that it does not recognise the .desktop files that I have created in users/appdata/local/applications for opening editors with the "open with" command.
Since our static code analyzers reported the *.desktop files as incorrect, we had to rename the entries for "Exec" and "Icon" because the Windows paths do not correspond to the freedesktop standard. Change Exec -> X-Exec and Icon -> X-Icon Maik
