Seems OK here.
SPlat 2016.10
EZD 2.1.1 (build 10513) 64-bit VST
Standard sound libs,
Modern version 1.0.2
Vintage version 1.0.2
I start SPLat (25 seconds! - Jamaica Plain (parallel install) starts in only 7 secs)
I start an empty BASIC project,
in Instruments/Drums I doubleclick on EZDrummer and say OK on the options dialog
EZD appears and is also there in the synthrack.
I click on the red 'X' in the synthrack and say OK in the confirmation dialog.
The EZD window disappears almost immediately and the synth rack entry follows 3 seconds later.
No crash. Tried it several times now.
Repeat with folder option,
Delete folder,
No change in EZD, no message appears lower right.
