A: Both the professional and standard versions are enclosed in the same program. Whether the program behaves as the professional or standard version depends solely on the activation key entered.
Q: As an owner of the 4.00 version, how do I get an update to a newer version of DataQualityTools?
A: As an owner of the 4.00 version, you can download and install the current version of DataQualityTools at any time. As long as you have a subversion of version 4 of DataQualityTools, you do not have to buy an update, since your activation key for the 4.00 version is also valid for the updates.
