When you try to install Navisworks, the installer lists Navisworks as already being installed, even though it is not. As a result, you cannot proceed and install Navisworks.
This problem can occur with Navisworks Manage 2010, Navisworks Manage 2009, Navisworks Review 2010, Navisworks Review 2009, Navisworks Simulate 2010 and Navisworks Simulate 2009.
An incomplete uninstall can sometimes leave residual registry keys that may cause the Navisworks installer to detect incorrectly that Navisworks has already been installed.
In order to resolve this issue, you must remove the following key from the Windows Registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products\39497741D131AAB48BF792993B746F9A
Once completed, you can proceed with the installation.
Note: 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.
Please let us know should you come across this issue and be unable to resolve it.
Thank you.
I had indeed this problem, but I had not the mentioned key.
So I looked for other keys and I found
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products\C49E3147F02E0000E93BFBC4813ADE6A]
"ProductName"="Autodesk Navisworks Manage 2010 (32 bit)"
and
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products\C49E3147F02E9040E93BFBC4813ADE6A]
"ProductName"="Autodesk Navisworks Manage 2010 (32 bit) English Language Pack"
By deleting this 2 keys (before exported them) the installation check was enabeled.

I can not thank you enough for posting this information. I accidental removed the directory for the Navisworks exporter plugin and could not get the re-installer to work. It continued to show the 64 bit install as "already installed"! I tried uninstalling Revit and Navisworks, reinstalling, registry cleaners only to finally find your post. I looked through the registry and found the entry linked to the Navisworks 64 bit exporter and deleted it and then tried to reinstall. Sure enough the 64 bit install was now showing it as an available choice. Now I can export from with the addon from Revit Architecture 2011 and MEP 2011 right into Navisworks. THANKS AGAIN!!!
