We've recently been evaluating Exchange 2007 and now want to go to the full 64bit install. We were uninstalling the trial but can't get the Unified Messaging component to delete due to an MSI error.Is it a straightforward process to install the 64bit version given that the trial has not completely uninstalled?Many thanks

You need to reinstall your server anyway because you are using a 32 bit version of windows when you installed the 32 bit version of Exchange Exchange 2007 64 bit only installs on Windows 2003 64bit If you are using an Exchange 64 bit trial you can just enter the product key and voila you have full exchange Deli
