Stupid question, but how do I know whether I have installed the 32 bit or 64 bit version of Exch2007?I dont have the original packaged download file. The machine does have a 64 bit processor btw with Windows 2003 64bit..

Only 64 bit Exchange 2007 can be a production. 32 bit version only for LAB function test.

Hello. I know 32bit should only be used in the lab. But from looking at the installation, how do I know if its the 32bit or 64bit? Basically we had an Exchange 2007 installed. Before we go any further I dont want to find out we have the wrong version down the line! Sound silly I know, but I have installed a 32bit version in a virtual environment and I can't see any obvious differences between them.

nn.. In 32 bit Exchange 2007 everytime you opent EMC will show you the product expire day and you cann't find "enter product key" icon in server configure level. In 64 bit before you enter product key it also will show you expire day when you open EMC,but you can find enter product key icon in server configure level..
