Obviously, you may need to change the Registry location depending on what version of Revit you are using…

If you don’t want to manually edit the Registry, you can use the CAD Manager Control utility as per this post:

If you are having Communication Center issues, it may be due to a corrupted XML file.  Refer to this Revit support page:
Revit 2010 products hang at or before splash screen

You are experiencing problems with the installation of an Autodesk product, and you want to enable verbose logging in order to troubleshoot the issue or submit the log files to the Autodesk Product Support Team.

You can configure the Microsoft Installer (MSI) to turn on verbose logging for this installation. Follow these steps:

  1. Click Start menu (Windows) > Run.
  2. In the Run dialog box, enter regedit and click OK.
  3. In the Registry Editor, browse to the following folder:

    HKEY_LOCAL_MACHINESoftwarePoliciesMicrosoftWindowsInstaller

    Note: Windows 7 does not include this key and you will need to manually add the Installer key to the registry. Right-click on the Windows subkey and choose New > Key and then rename New Key #1 to Installer.

  4. Right-click an empty area in the right pane. Click New > String Value.
  5. Enter Logging for the name.
  6. Double-click Logging.
  7. Enter voicewarmup in the Value Data box and click OK.
  8. Close the Registry Editor, and run the installation again.


The log files created using this method are located in the %TEMP% folder and are named MSI#####.log, where ##### is a 5-digit number.

A previous attempt to install or uninstall an Autodesk® product failed to successfully complete and now you are unable to install or reinstall an Autodesk product on your system.

Solution
In these cases, it is strongly recommended that you clean your system by uninstalling all Autodesk products and supporting applications (add-ins, utilities, enablers, etc.), and by removing related files and settings before attempting to reinstall. The end result is a clean system on which you can install your new Autodesk product.

This is pretty drastic stuff, but sometimes it is the only way…

Scenario

Issue
You were creating a cross-platform deployment, i.e., a 32-bit deployment on a 64-bit OS or vice-versa, and you added two different language packs to the deployment causing the installer to display the following error message and crash:

Solution
When creating a cross-platform deployment, only add one set of language packs to the installer per session of setup.exe. If you need to create the deployment in an additional language, you should do so in a separate session of setup.exe by launching the installer from the media and then adding a single language pack.
