I am having trouble registering GDViewerPro4.ocx on Windows XP, I get error 'The applicationor DLL c:\WINDOWS\system32\gdViewerpro4.ocx is not a valid windows image'. This is for a VB6 application and I only get this when installing using setup.exe. If you manually register using regsvr32 it works fine. As per technical reference, the installer copies gdpdfplug.dll and gdimgplug.dll to system32 but does not register them. It is installing on XP so don't copy or register GDIPLUS.dll. GDViewerPro.ocx is copied to system32 and registered by installer.
Any ideas appreciated.
