Hello! First post, long time reader
for those that cant select the dll file:
~open cmd window (start menu and type cmd in search box) then right click and run as admin
~type in (or paste) regsvr32 "C:\LG Electronics\LGNPST\Model\MTP\MS690.dll" (if that is your path, if not, change it accordingly)
~open LGNPST, and your file should be in there.
Hope this helps
