Registry value for ServicePackLevel

Hi,

I'm a user of IDE 8 Basic MSI Projects. Some time ago I have made an installation package that runs on Win XP SP1. I used property 'ServicePackLevel' in InstallScript setup.rul file as install condition.

Now SP2 for Win XP is available I discovered that my installation contained a serious bug. It does not allow to install on Win XP SP2 because it doesn't test 'ServicePackLevel' = 2.

I thought, let's fake the OS and find the registry value which is used to fill the 'ServicePackLevel' property. But I can't find it. Changing the registry key 'HKLM\SOFTWARE\Microsoft\Windows NT\Current Version' and key 'CSDVersion' does not help, even after changing it and restart the computer.

Can anybody please tell me how 'ServicePackLevel' property in MSI is filled from the registry? Or is it taken from an installed file somewhere in C:\WINNT ? Thanks in advance.

Regards,
kermit
