Warning! Problems caused by improperly editing the Windows registry could render your computer operating system unusable. Microsoft provides a wealth of critical information that you need to know about the registry in the Microsoft Knowledge Base at http://support.microsoft.com.
Use the Microsoft® Registry Editor only at your own risk and only after backing up the registry as well as the system.dat and user.dat files as outlined for your operating system in the Microsoft Knowledge Base and in the related solution, TS66513. Additional information about the registry is also contained in the Help topics in the Microsoft Registry Editor.

Before reinstalling Revit products
- In Windows Explorer, delete the contents of your Windows Temp folder, but do not delete the Windows Temp folder itself. You can locate the Temp folder by entering %TEMP% in the Address bar of Windows Explorer.
- Use the End Task feature to end any anti-virus programs.
Note: Disabling anti-virus programs from the system tray may not be sufficient. Virus checking programs may block certain activities that are seen as suspicious (for example, accessing the registry, adding/removing/updating DLL files, and so on), even though these activities are common when installing or removing programs.
Several anti-virus programs can be disabled by right-clicking the taskbar icon and selecting Disable from the shortcut menu. For more information about disabling your anti-virus software, refer to the vendor of that software.
Important! It is important that you not only disable the anti-virus software but also use the End Task feature to end the anti-virus software.
To verify that an anti-virus program is not still running in the background as a TSR (Terminate and Stay Resident Program):
Windows XP, Windows Vista and Windows 7
- Press [Ctrl] + [Alt] + [Delete].
- Click Task Manager.
- On the Processes tab of the Task Manager, select the process for the anti-virus program and then click End Process.
You are now ready to install Revit 2011 products on the clean system.
