MapWinGIS-only-v5.0.1.9-Win32 on Vista

After installation I cannot register the OCX on Windows Vista Ultimate 32-bit: after regsvr32 \mapwingis.ocx I get the error: ‘Cannot load module \mapwingis.ocx’
Anything that I miss here?

(on Vista Enterprise SP2 64-bit same result)

Note: Dependency Walker shows GDAL203.dll has unresolved import due to missing export function…

Hello @Koos

A couple questions (forgive me if they sound trivial):

  1. Outside of the unresolved import issue, does Dependency Walker indicate that GDAL or any specific DLL was unable to load or be resolved? If so, can you verify whether or not the DLL(s) is/are present?
  2. Did you run regsvr32 from a command prompt ‘as Administrator’?

Thank you,
Jerry.
