Microsoft: Exchange 2007 – The Microsoft Internet Information Service is in 32-bit mode and this is a 64-bit computer.

By re-installing Client Access Role (CAS) on my Windows 2003 R2 Enterprise 64 bit and Exchange 2007 Enterprise machine I get:

“The Microsoft Internet Information Service is in 32-bit mode and this is a 64-bit computer. The mode must be changed before Setup can continue”

Resolution:

To switch IIS to 64-bit mode:

1. Open a command prompt.
2. Type the following:cscript c:\inetpub\adminscripts\adsutil.vbs SET /w3svc/AppPools/Enable32BitAppOnWin64 False
3. Press enter

Now can I finish my installation
