Error 1406 during Inventor® install

When you tried to install an Inventor® product, you received the following error message:

Error 1406. Could not write value to key
\Software\Classes\CLSID\{D27CDB6E-AE6D-11cf-96B8-444553540000}\Programmable.
Verify that you have sufficient access to that key, or contact your support personnel.

This error occurs if you have Macromedia Flash Player 8a installed on your system. This version of Flash Player is newer than the version that is installed with Inventor®. 

Before you install Inventor, you should check to see which version of Flash Player is installed on your computer. If you have version 8a installed, you should uninstall it before you install Inventor. Because Flash Player 8 is installed during the Inventor installation, you will have a working version. Future Flash Player upgrades should not affect your Inventor environment.

To correct this issue

  1. Cancel the installation of Inventor.
  2. Close all of the Internet browser windows you have open.
  3. On the Start menu (Windows), click Run.
  4. In the Run dialog box, enter C:\WINDOWS\system32\Macromed\Flash\UninstFl.exe to clean all Flash 8a registries. Note: Make sure to enter the entire path.
  5. On the Start menu (Windows), click Settings > Control Panel.
  6. In Control Panel, double-click Add or Remove Programs.
  7. In the Add or Remove Programs dialog box, select Macromedia Flash Player 8. Click Remove. Note: Although Flash Player 8 is listed, this is really version 8a.
  8. Retry Inventor installation.

If you are still not able to install Inventor successfully, please contact Product Support for further assistance.
