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.

2. Read the information on the file you are trying to open, and make sure that your file is the only one needed and that it is not part of a series of files (like part 1 of 3). If it is a part of a series, you will need to download all of the files for your movie and then try to play the file again.

3. Download the InterVideo DVD XPack plug-in and follow the installation instructions if you are running XP on your computer. The InterVideo DVD XPack will decode your DVD and provide Windows Media with any additional codecs that might be needed to play it.

7. Restart your computer and install your program.

1. Close all of the other programs that are running and try again. Sometimes programs don't work well together. You may have to open the Task Manager by hitting 'Ctrl Alt Delete' to access the list of running programs. From here, you can close down programs running in the background that you may not need.
2. Restart the computer. If closing down other programs didn't work, often a restart will resolve the problem. After you have restarted, don't do anything else before attempting the operation again. This will reduce the possibility of other programs interfering.

3. Run the Scandisk program that comes with Windows. There may be some errors on your hard drive that are causing fatal errors. Sometimes Scandisk can fix the hard drive problems and prevent the error from occurring again.
4. Go to Windows Update and download the latest files if you are not currently up to date with all of the patches and service updates. Windows will automatically determine which updates you need.
5. Uninstall any recently installed software. The software may have a problem or might have installed incorrectly. It also just might not work well with other programs.
6. Take out the RAM and take it to a computer store to see if there are any problems with it. You can try replacing the RAM without having it checked, because RAM is relatively inexpensive. But if you can find a computer dealer that has a RAM tester, you can usually get your RAM tested for free.

9. Click 'Yes' when prompted.
10. Double-click the installer package that was previously generating the error. You will no longer have any issues with it.

1. Check the time and date to which your computer is set. Occasionally certificate errors occur because a computer is set to the wrong date and/or time. In Vista, the time is located in the bottom right-hand corner. The date appears when the cursor is placed over the time and allowed to hover. If either are incorrect, double click on the time. A small window with the date and time will appear. Enter the correct date and/or time.
2. Refresh the website.

3. If the certificate error still appears and the address bar still has a red background, click on the padlock located next to the address bar.
4. A window will appear that informs you about the certificate. This information will include the website's title, whether the owner is verified or not, and whether the location has been verified or not. You will also be informed whether or not much information is known about the website and how trustworthy it is.
5. Compare the information provided in this box with what you know about the site. If the two pieces of information don't match up, the site is not secure. You can choose to navigate away from the page or to bypass the certificate error and use the site.
