NSPR4.dll, MOZCRT19.dll or PLC4.dll is Missing From Your Computer? Fix it!

Today, I clicked on a popup window in Google Chrome and received the error “The program can’t start because NSPR4.dll is missing from your computer. Try reinstalling the program to fix this problem.”. Here’s how you can fix the problem.

For some reasons, some situations can trigger this DLL error.

1. Step Open Windows Explorer (Windows key + E)
2. Go to C:\Program Files (x86)\Mozilla Firefox, locate and select nspr4.dll, mozcrt19.dll and plc4.dll
3. Copy all three DLL files to the folder C:\Users\[username]\AppData\Local\Google\Chrome\Application\9.0.597.47 – replace 9.0597.47 with your Google Chrome version and [username] with your actual username
4. Repeat the same for any other DLL files that are missing from your computer.

This can help to fix the error. However, if you run into any other problems you will need to do a complete reinstall. Remove Google Chrome from your computer. Download the latest Chrome version and install it after rebooting your PC.
