About Resetting the Application to the Default Settings

The settings of the program can be restored to their original installed values, this can be helpful when trying to resolve a problem with the program.

When resetting the program, the values stored in the Windows Registry along with the files in the Roaming and Local Root folders are removed. Upon the removal of the values and files, the secondary installer is started. The secondary installer adds the default values to the Windows Registry and copies files from the UserDataCache folder to the proper locations in the Roaming and Local root folders for the program.

Note: It is not recommended to edit the Windows Registry directly.

The following Windows Registry entry is removed during the reset:

• AutoCAD: HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R22.0\ACAD-1001:409
• AutoCAD LT: HKEY_CURRENT_USER\Software\Autodesk\AutoCAD LT\R24\ACADLT-1001:409

Note: The value 1001:409 varies based on which product and language is installed. For example, 1001:804 represents the Simplified Chinese version of the product.

The following user folders are removed during the reset:

• Roaming Root Folder

  <drive>:\Users\<user name>\AppData\Roaming\Autodesk\<product name>\<release number>\<language>

• Local Root Folder

  <drive>:\Users\<user name>\AppData\Local\Autodesk\<product name>\<release number>\<language>

Note: The Migration folder created by using the Migrate Custom Settings utility or after importing a transfer package is not removed during the reset.

Backup Files

If you choose to back up your custom settings and files before resetting the program, all files in the Roaming and Local root folders are backed up with the following exceptions:

• *.tmp – Temporary files
• *. err – Error files
• *.cache – Material cache files
• support.cdc – DesignCenter cache file
