You can determine the build of the Visions product in multiple ways. If you are logged into a Dynamics GP company, all you have to do is click on the mc² logo on any mc² window. If you are not logged into Dynamics GP, simply right-click on the Visions the dictionary version in one of the other tabs.
If you want, you can automatically display the build information in the Details view in Windows Explorer. Simply open the Dynamics GP folder in Explorer, select Choose Details under the View menu, scroll down the items, mark Dictionary Version and click OK. (This will work only in some versions of Windows, as not all of them have the Dictionary Version option.)
