Exchange 2007 RTM and SP1 are available in two platform versions: the 64-bit version is for live production environments, and the 32-bit version is for non-production environments, such as labs, training facilities, demos, and evaluation environments. Only the 64-bit version can be purchased because you cannot run 32-bit Exchange 2007 servers in production.
NOTE: To open 64-bit Offline Exchange 2007, 2010, 2013 or 2016 databases, you must install DigiScope® on a 64-bit operating system.
If you are running the 32-bit version of Exchange 2007, the steps are exactly the same as outlined in Adding Exchange Files; however, after designating the 32-bit database and its associated log files, DigiScope® will present the Exchange 2007 Database Warning dialog as shown below.
Click the Yes button to continue and DigiScope® will enable 32-bit support.
The Missing Exchange DLLs dialog will appear so that you can acquire the required 32-bit DLLs from an Exchange 2007 32-bit server. Click here for more information.
Complete the rest of the wizard as outlined within "Adding Exchange Files".
