I had a program from Magix called Connect installed in C:\Program Files (x86):
I think this was installed for the first time along with installing Vegas Pro 15 build 177.
It was also in the Task Scheduler section of my AutoRuns listing, indicating that it was getting run automatically at some point.
I think I just inadvertently uninstalled it by double-clicking it in Control Panel > Programs & Features to try and run it. I never thought that would just uninstall it without at least a prompt.
The installer for it is still sitting in my Documents > MAGIX Downloads > Installationsmanager folder:
Does anyone know what this is? I guess it could be to do with the Vegas Pro Connect app for iPad, but I think it more likely that it is something that connects to Magix for licensing or "news" purposes.
