After installing Revit Architecture Suite 2010, I was suprised to find out that my install of Architectural Desktop 2007 would no longer allow me to drag and drop palettes from the content browser to the application. Since the “AutoCAD” native import and export of tool palettes is disabled in the vertical products, I was left with attempting to rebuild tool palettes one tool at a time. This is unacceptable and left me without a means to re-build or extend some standard palettes in use by a large number of users. It also was an ALL Stop issue related to pushing out Revit Architecture 2010 to others in the firm.
After failing to uncover a hotfix, service pack, or mention of the problem related to ADT 2007 I resorted to standard processes. I attempted the fix on my own by doing the repair option. When this failed I resorted to the standard uninstall/reinstall dance. When that too I attempted a more vigorous repair option, this time by uninstalling all Autodesk products, purging the known hideouts and registry entries and then reinstalling in order of release.
Since none of these steps worked, I submitted a trouble call to Autodesk Web Support. While I waited for a response, I prepped my machine for a clean wipe and re-image for the hard drive. I was pleasantly surprised when Autodesk responded with an “as yet” unpublished Hotfix (see the Archidigm link). This am, I applied the Hotfix and was once again able to drag and drop palettes into ADT2007.
This fix is easy to apply, simply rename the offending file in the Autodesk Shared folder and copy in the new dll. You can get them at Archidigm or wait for Autodesk to post them.
