Note: You should not apply this update to a computer that has not experienced these errors, or to a computer that does not contain a Serial ATA hard disk controller. If you experience these errors with an Autodesk product, but your computer does not have a SATA hard disk controller, please contact your dealer. 

The problem does not affect products prior to the versions listed.

1. On the Windows XP Start menu, click Run. On Windows Vista, press [Windows key] + R.
2. In the Run dialog box, enter MSINFO32. Click OK.
3. In the System Information dialog box, expand Components > Storage.
4. Select SCSI. (SATA disks are listed as SCSI by the Windows System Information Report.)
5. Under SCSI, check to see if any of the controllers' names contains either SATA or Serial ATA.
