Autodesk’s Revit software does not directly display what software update or service pack has been installed on the computer. Instead of listing the actual update number, Revit displays the Build number which is a bit cryptic. You really don’t know whether you have the current update simply by looking at the build number, but you can tell the date of the build. It is good to check this build number to make sure that you have the current build for your version of the software as this is one of the first things to check when you are having problems with your Revit installation.
To determine the Build number, select the drop-down list arrow to the right of the question mark Help button at the top of the opened Revit application. From the list, select the About option at the bottom of the list. At the top right corner of the dialog box that just opened, you will see the Build number.
The first four characters of the build number are the build year, following by the 2-digit month and the 2-digit date. Build 20090917_1515 is the September 17, 2009 version. It does not tell you that this was Update 2.
