Additionally, if you inadvertently install UR4, and later realize that you want to load R2, you will need to uninstall Revit, reinstall, and then install R2.Īdditional Note: As mentioned in the installation readme for UR4 (and R2) the update requires either the initial release of Autodesk Revit 2015 (build: 20140223_1515) or Autodesk Revit 2015 Update Release 3 (build: 20140606_1530). Note: You cannot install both UR4 and R2. R2 includes all of the updates included in Update Release 4 (and after installing will show Update Release 4 in the About Revit dialog), but also has added functionality available only to Autodesk Maintenance and Desktop Subscription customers. If you look on the Subscription Center, you will find Autodesk Revit 2015 R2 (released ). If you look on the Revit download page, you should see that the latest 2015 update available is Update Release 4 (released ).
