Hello, just want to report a possible bug.
The installer (vstoolsforxamarin.exe) upon launch will ask for install path. I changed it to another drive as my first one did not have room to hold the estimated 29GB required. Actually, I changed the install path to a folder that had another volume mounted with enough storage.
The installer proceeded to install some things in the new location, however most of the bundled tools after were installed back under the default of C:\Program Files\, filling up my main drive.
Needless to say, this caused undue time to be wasted as i had to shuffle drives around and restart in install with a bigger main drive.
