So what happens when you have an x64 development box running Windows 2003 R2 x64 Enterprise with IIS6 in WOW64mode and you want to install the 32bit version of WSS 3.0?
Setup is unable to proceed due to the following error(s):
– This 32-bit product must be run on a 32-bit Operating System. For 64-bit support, please install the 64-bit version of this product.
– Internet Information Services is running in 32-bit emulation mode.
Correct the issue(s) listed above and re-run setup.
