it shouldn't matter where the vst is installed (c drive, d drive, f, g h, ...)
it is also good practice to put your VSTs outside the "program files" folder hive, as that folder hive has extra security which can cause issues (I'm still suprised the main daws still default to this)
having said that, breverb does look like the issue - is it an existing poroject or inserting it into a new project?
