How to Uninstall SPTD

Save

When you install some applications that interact with your computer's CD or DVD drive, the process may also install the SCSI Pass Through Direct (SPTD) driver. The driver loads each time you boot your computer and can sometimes cause stability problems when it conflicts with other drivers. Although the driver often comes with virtual CD drive programs, uninstalling the program itself may leave the driver behind. You can easily use SPTD's setup file to remove the driver from your system.

  • Launch your Web browser and navigate to the Duplexsecure.com/downloads page. Click the first download link if you have the 32-bit version of SPTD installed or the second link if you have the 64-bit version. Click "Save" on the download prompt, then select the location to save the downloaded file.

  • Double-click the downloaded setup file for SPTD, then click "Yes" if you get a User Account Control prompt. Click "Uninstall" on the window that opens, then click "OK" to confirm you want to uninstall SPTD from your computer.

  • Click "OK" after the process completes, then restart your computer to finish uninstalling SPTD.

Tips & Warnings

  • To find out if you have the 32-bit or 64-bit version of Windows, click the Windows "Start" button, then right-click "Computer" and select "Properties." Look to the right of "System Type" under the "System" section of the page. If you have the 32-bit version of Windows, you should download the 32-bit version of the SPTD setup program.
  • If you download the 32-bit version, but have the 64-bit version of SPTD installed, you may get an error message when you try to uninstall the driver. If this occurs, download the correct version of the SPTD setup file for your system and try again.
