No GUI with VST2 on Ableton Live 9.7

[thereblight]

I installed Surge with the windows binary from the release page here. When I put the plugin on a midi track in the ableton live, it's loaded, it makes sound and I can even access the parameter list, but there's no Plug-in Edit button for opening the GUI. I assume that ableton sees Surge as a GUIless plugin.

• OS: Windows 10
• Host: Ableton Live
• Version: 9.7.7

I tested it on other hosts that I can get my hands on (Reaper 5, Studio One 3) and there was no problem.

(FYI, I couldn't find any option for selecting the vst plugin folder path during the installation, and it took me a while to find out that the dll was installed on the folder C:\Program Files\Common Files\VST2. I just copied the file to my designated folder and all is good, but I think that the installer can get more polished.)
