If you are using more than one Autodesk SSO, you may come across this problem…

  • After a Windows Update or something similar, Revit is not responsive after first launch. Clicking has no effect, but there is no dialog shown either.
  • You may investigate the process details and determine that LMU.exe is thrashing, and you could look at log file in C:\ProgramData\FLEXnet and see it growing. You can also observe something like this in the Revit Journal file:
    ‘C 08-Aug-2017 14:53:49.479; 0:< manage licensing
    ‘C 08-Aug-2017 14:54:03.845; 0:< License checkout failed: 20
    ‘C 08-Aug-2017 14:54:03.845; 0:< License cleanup skipped
  • This is telling us there is a licensing problem. In this case, a perpetual license has somehow become deactivated. What is the fix?

You need to login with Autodesk SSO login credentials that have the Perpetual license for that product available…

To do this:

  1. Start Revit Viewer for the same year version that is causing the problem, such as Revit Viewer 2015
  2. Use the top right panel to logout and login with the correct SSO (login credentials)

  3. Then, attempt to launch the full Revit application
  4. It should re-activate itself now that the correct login credentials have been used
  5. You can probably switch back to other credentials now that the activation has occurred

You can also use the A360 icon to sign in, this may be more reliable in some cases:

Yet another situation where you need to know What Revit Wants 🙂

You need to move your Stand Alone Autodesk license to a new computer, either permanently or temporarily.

Solution

Most Autodesk products (including those available for Mac) include a tool called the License Transfer Utility (LTU) that enables online license transfer of stand-alone licenses from one machine to another over the Internet.
Note: The LTU is only available with our 2010 and later products. If you’re using a 2009 or earlier version, use the Portable License Utility instead.

The License File Parser allows you to easily convert the contents of your Autodesk license file into an easy to read report. Among other pieces of useful information, the report contains the full name of the licensed product, the serial numbers, and the number of seats.

Issue

Your stand-alone Autodesk product licenses have become corrupted and you want to know how they can be reset.

Solution

Use the following steps to reset the stand-alone licenses for all Autodesk products (version 2010 or higher):
1. Make sure there is no Autodesk product currently running.  If there is, close the application.
2. Rename the adskflex_00691b00_tsf.data file to adskflex_00691b00_tsf.data.old.  This file can be found at the following locations:

Windows XP
C:Documents and SettingsAll UsersApplication DataFLEXnet

Vista/Windows 7C:ProgramDataFLEXnet

3. Restart your Autodesk product and go through the activation procedure again.
Note: This file contains all product activations for all 2010 and higher Autodesk products installed on your system.  You will need to re-register these products if this file is renamed/deleted.
