Hope you are well.
Just got a new laptop with shiny new Vista Home Edition installed, cool...or not as the case may be! Had some serious issues which are hopefully solved now.
During testing I encountered an error installing 'Boxing Manager Professional Edition'. A quick net research proved this to be a common Vista problem regarding installation of OCX files.
The official line on the pcboxing.com website is:
VISTA USERS NOTICE
Strange bug encountered on Vista Home Edition displaying file not registered, invalid or missing message.
Goto Windows/System32 folder & rename 'nslock15vb5.ocx’ file.
Reinstall BMProSetup.exe and Voila, Fixed!
Hope this helps any of you that have recently come across this prob.
