How to detect Windows 2003 Server Standard Edition

[rootme]

Hi

In a project I'm developing I have to allow to install a module only if the OS is Windows 2003 Server Enterprise Edition and not to allow the install if the OS is Windows 2003 Server Standard Edition.

I detect Windows 2003 Server by using (SYSINFO.nWinMajor = 5 && SYSINFO.nWinMinor = 2) but how do I detect witch Edition ?

Thanks

You might see if SYSINFO.nSuites or other SYSINFO fields can help; the MSDN help for OSVERSIONINFOEX (there's a link on the SYSINFO help topic) describes combinations that describe various OS varieties.

Hi

Found (SYSINFO.nSuites & ISOS_ST_ENTERPRISE) and (SYSINFO.nSuites & ISOS_ST_DATACENTER) ... but I don't find for STANDARD EDITION.

Why doesn't this work ? (SYSINFO.WINNT.bWinServer2003 = TRUE) & (SYSINFO.nSuites & ISOS_ST_ENTERPRISE) ? It doesn't detect Win2003 server enterprise edition .... if I use only (SYSINFO.nSuites & ISOS_ST_ENTERPRISE) it detects that it is an enterprise edition.


Thanks

Perhaps try to join the two pieces with logical-and (&&):

(SYSINFO.WINNT.bWinServer2003) && (SYSINFO.nSuites & ISOS_ST_ENTERPRISE)
