Windows 7 64bit nslookup

This version of C:\Windows\system32\nslookup.exe is not compatible with the vers
ion of Windows you're running. Check your computer's system information to see w
hether you need a x86 (32-bit) or x64 (64-bit) version of the program, and then
contact the software publisher.

I get the following error above when trying to launch nslookup from command prompt.  When I try to run it from the syswow64 folder it works but from command prompt I get the above error. How can I fix this?

Have you tried going to the nslookup.exe, right-clicking and telling it to run in 32bit mode or xp-compatibility mode by default? This might help.

Odd, my nslookup which is standard win 7 x64 works fine, perhaps a different version has been copied over the correct one at some stage? Try copying back from a working Win7x64 machine.

How do you launch command prompt?

My wild guess is that you have launched the 32 bit command prompt and of course nslookup.exe in c:\windows\system32 will not work as the system utilty in that folder ia in fact of 64 bit instead if 32 bit whereas nslookup.exe file in syswow64 folder is of the version of 32 bit.

If it used to work fine, just launch system restore to go back to a restore point when there was no problem.

First, if you launch the Windows command line (cmd.exe) on a 64-bit edition of Windows 7 and then look at the Task Manager, you'll notice that the process entry for cmd.exe does not have an *32 after it. This indicates that the cmd.exe process is 64-bit.

Is your comand prompt 32 bit or 64 bit?
