Today I was trying to install Sharepoint Services 3.0 with SP2 on a Windows 2008 R2 X64 machine. Setup would not run as I got the error:
Setup is unable to proceed due to the following error(s):
Internet Information Services is running in 32-bit emulation mode.
Correct the issue(s) listed above to re-run setup.
So basically it looks like by default Internet Information Services is installed in 32 bit-emulation mode.
To disable this you simply need to do the following:
open a command line
copy and paste the following-
CScript "%SystemDrive%\InetPub\AdminScripts\adsutil.vbs" set w3svc/AppPools/Enable32bitAppOnWin64 0
Then type IISreset
Then try to re-run setup for Sharepoint Service 3.0 with SP2
