Issue:

Causes:

This error can have several causes:

• The Licensing services are disabled
• A corrupted installation of an Autodesk program.
• The registry was adjusted to change the license method.
• The Trusted Storage files are corrupted.
• The installation of the product is corrupted, including important registry information.
• There are permission issues on important locations that manage the licensing mechanism.

Solution:

1. Click the Windows Start button and in the Run box type "Services"
2. Select the "Services" node
3. In the services list, locate FlexLM Licensing Service and FlexLM Licensing Service 64
4. Right-click the entry and click "Properties"
5. Set the "Startup Type" to "Automatic"
6. Click "Start" to start the service and click "OK"
7. Do this for both services. (32 bit systems may have only one servce)
8. Start the program to test

1. Look for a specific xxx_TSF.data file, such as ADSKFLEX_NUMBERS_TSF.data.

Location in Windows XP:
Documents and Settings\All Users\Application Data\FLEXnet

Location in Vista and Windows 7:
C:\ProgramData\FLEXnet

2. Change the file extension to something such as ADSKFLEX_NUMBERS_TSF.data.BAK or completely move it from this folder. (Don’t destroy it, just get it out of the way.)
3. Start the program. A new xxx_TSF.data file (and possibly a log file) will be created.
4. If the program works, you are finished.

5. Start the program. Register the program as requested.
