Update the Drivers
1. Boot your computer in safe mode. To do so, press the power button to turn the computer on and press the “F8” key every few seconds until the “Advanced Boot Options” appears. Use the down-arrow key to move through the boot options; choose “Safe Mode” and press “Enter.”
2. Open the “Start” menu on your Windows system. Click “All Programs>Accessories>Run” to open the “Run” function.

3. Enter “wupdmgr” in the “Run” box and press the “Enter” key on the keyboard. Windows searches the Internet for updates available for the operating system, and installs the updates automatically.
4. Launch the program that keeps displaying the System32.Dll error message from “Start>All Programs.” If the program launches without an error message, the System32.Dll file was replaced during the update.
Replace the File Manually
5. Download a new System 32 Dll file from a Dll file library. Since you won’t have access to the Internet in safe mode, you must do this on another computer. Dll file libraries where you can download a System32.dll file for free include DLL Download System, DLL Files and DLL Nerd (see Resources).
6. Go to the folder where the downloaded System 32 Dll file is saved, which is more than likely the system’s “Downloads” folder. Right-click on the System32.dll folder and select “Extract” from the menu to pull the actual files from the System32.dll folder.
7. Plug an external storage device, like a thumb drive, into the computer you used to download the System32.dll file. If the device folder doesn’t open automatically, go to “Start>Computer” and double-click the thumb drive in the drive list.
8. Return to the “Start” menu and click “Computer” again. Double-click the “C:” drive, go to “Users,” double-click the folder of the user account on which the Dll file was downloaded and double-click the “Downloads” folder. Drag and drop each of the files from the “Downloads” folder to the external hard drive folder.
9. Remove the external hard drive from the computer where you downloaded the System32.dll file and plug it into the computer that is missing the System32.dll file. If the external hard drive folder doesn’t automatically open, go to “Start>Computer” and double-click the drive to open it. Open the computer’s “Start” menu. Go to “Computer>C:>Windows>System32” to open the “System32” folder. Drag the System32.dll file from the external hard drive window into the “System32” folder. Click “Yes” if asked if you want to replace the original System32.dll file.
