Installing run-time engine 7.0 on windows NT

[Mashkas]

I attempted to Install Labview run-time engine 7.0 (LVRunTimeEng), on windows NT with workgroups 4, but got the message wrong OS. I am sure I downloaded the correct version (which is supposed to support Windows NT). Anyone have the same problem ? Anyone know how to fix it?
Thanks in advance

This message comes from the MSI installer engine. The engine requires Service Pack 6 to be installed on NT 4.0 systems. Can you verify that you have this service pack.

Thanks a lot Naren!
I can't check this right now, but if I am missing Service Pack 6.0 do you know where I can look for it?
Thanks in advance
