AutoCAD splash screen starts up and then closes (Standalone)

Issue

When running the software, it becomes unresponsive and freezes your computer. When you restart the computer and you try to restart AutoCAD, the splash screen starts up and then closes down with no apparent error message.

This symptom is very similar to TS14908069.

Solution

1. Check the file "productname201xENUAdlm.log" located here:

   Windows XP
   C:\Documents and Settings\All Users\Application Data\Autodesk\ADLM

   Vista/Windows 7
   C:\ProgramData\Autodesk\ADLM

2. The error will typically be:

   Reason=Fatal error
   ComputerName=COMPUTER
   OS=5.1.2600.Service Pack 2
   File=AdlmIntSATSLicense.cpp,Line=1150
   AdlmIntError=38 [Error getting license usage and behavior]

   Reason=Fatal error
   ComputerName=COMPUTER
   OS=5.1.2600.Service Pack 3
   File=AdlmIntSATSLicense.cpp,Line=347
   VendorID=2 [ADLMACT]
   VendorError=101 [The license cannot be accessed/loaded/opened]

This indicates that the ADLM trusted storage file has been corrupted when AutoCAD crashed.

3. Rename the following file by adding a .bak extension at the end of the filename.

   Windows XP
   C:\Documents and Settings\All Users\Application Data\FLEXnet\adskflex_*_tsf.data

   Vista/Windows 7
   C:\ProgramData\FLEXnet\adskflex_*_tsf.data

This file contains all activations for all 2010 and 2011 products.  You will need to re-register all your products if this file is renamed/deleted.

4. Restart AutoCAD and it will automatically re-register via Register Today and it will start up as expected.   A new adskflex_*_tsf.data file will be created when you re-register your product.
