Check whethere Vista or not

[agyr77]

Hi,

There is scenario below:

OS: Windows Vista Ulimate

1) An Installation was setup - Vista detected perfectly!!!
2) Then this Installation was uninstalled
3) Second attempts of the Installation detected that the OS is XP (Windows version 5.1) not 6.0 as it is expected

The script code that detects what OS is

RegDBSetDefaultRoot( HKEY_LOCAL_MACHINE );
RegDBGetKeyValueEx( "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion","CurrentVersion", nOS, svOS, nvResult);
MessageBox("CurrentVersion is: "+svOS, INFORMATION);

I will much appreciate help to this collision
Thanks

Hello agyr77,

I allways use the properties VersionNT and WindowsBuild.
