GetDLLVersionLocal error in 1.6b2
I'm using NSIS 1.6 beta 2 and I'm trying to use the new GetDLLVersionLocal command. I may be doing something wrong but I get the following error when trying to compile:

GetDLLVersionLocal: error reading version info from "getfolder.ocx"

There is nothing wrong with my file, and I have even tried using the included upgradedll.nsh to do a test "upgrade" but the same error presents itself. Maybe someone who has it working can post a full example .nsi script using the function so I can see if I'm doing something wrong. Thanks.

my code excerpt:
SetOverwrite try
StrCpy $0 "c:\getfolder.ocx"
UnRegDLL $0
!define DLL_NAME getfolder.ocx
!include upgradedll.nsh
RegDLL $0
