How to get the full Groove installer
by Volker Weber
Do one install. After it has finished downloading, it will ask you to start installing.
Take a break here. Find a file called TempGrooveWorkspacePreview.exe. Make a copy of that file. It is the full installer.
If you are trying to upgrade an existing installation it will download a file called GrooveUpgrade.exe. Again it will ask for confirmation to start the upgrade. If you make a copy of that then you have both.
