Why does SetupDiEnumDriverInfo give two version numbers for my driver

Question

I\'m trying to get the version number of a driver programmatically. The seems to be done by using SetupDiEnumDriverInfo to get a SP_DRVINFO_DATA st

As your code is written, all the possible drivers will be output. Try doing the following to filter on only the installed driver:

SP_DEVINSTALL_PARAMS InstallParams;
if ( !SetupDiGetDeviceInstallParams( devInfoSet, &devInfo, &InstallParams ) )
{
   //Error
}
else
{
   InstallParams.FlagsEx |= DI_FLAGSEX_INSTALLEDDRIVER;
   if ( !SetupDiSetDeviceInstallParams( devInfoSet, &devInfo, &InstallParams) )
   {
      //Errror
   }
}
