How to Fix Jscript.dll Errors

Do not download jscript.dll from a "DLL download" website. There are many reasons why downloading a DLL file is a bad idea. If you need a copy of jscript.dll, it's best to obtain it from its original, legitimate source.

Start Windows in Safe Mode to complete any of the following steps if you're unable to access Windows normally due to the jscript.dll error.

  1. Restore jscript.dll from the Recycle Bin. The easiest possible cause of a "missing" jscript.dll file is that you've mistakenly deleted it.
    1. If you suspect that you've accidentally deleted jscript.dll but you've already emptied the Recycle Bin, you may be able to recover jscript.dll with a free file recovery program.
    2. Recovering a deleted copy of jscript.dll with a file recovery program is a smart idea only if you're confident you've deleted the file yourself and that it was working properly before you did that.
  2. Run a virus/malware scan of your entire system. Some jscript.dll errors could be related to a virus or other malware infection on your computer that has damaged the DLL file. It's even possible that the jscript.dll error you're seeing is related to a hostile program that's masquerading as the file.
  3. Use System Restore to undo recent system changes. If you suspect that the jscript.dll error was caused by a change made to an important file or configuration, a System Restore could solve the problem.
  1. Reinstall the program that uses the jscript.dll file. If the jscript.dll DLL error occurs when you use a particular program, reinstalling the program should replace the file.
    1. Try your best to complete this step. Reinstalling the program that provides the jscript.dll file, if possible, is a likely solution to this DLL error.
  2. Run the sfc /scannow System File Checker command to replace a missing or corrupt copy of the jscript.dll file. Because this DLL file is provided by Microsoft, the System File Checker tool should restore it.
  3. Install any available Windows updates. Many service packs and other patches replace or update some of the hundreds of Microsoft distributed DLL files on your computer. The jscript.dll file could be included in one of those updates.
  4. Update the drivers for hardware devices that might be related to jscript.dll. If, for example, you're receiving a "The file jscript.dll is missing" error when you play a 3D video game, try updating the drivers for your video card.
  1. Roll back a driver to a previously installed version if jscript.dll errors began after updating a particular hardware device's driver.
  3. Repair your installation of Windows. If the individual jscript.dll file troubleshooting advice above is unsuccessful, performing a startup repair or repair installation should restore all Windows DLL files to their working versions.
  4. Use a free registry cleaner to repair jscript.dll related issues in the registry. A free registry cleaner program may be able to help by removing invalid jscript.dll registry entries that might be causing the DLL error.
  1. Perform a clean installation of Windows. A clean install of Windows will erase everything from the hard drive and install a fresh copy of Windows. If none of the steps above correct the jscript.dll error, this should be your next course of action.
  2. Troubleshoot for a hardware problem if any jscript.dll errors persist. After a clean install of Windows, your DLL problem can only be hardware related.
