OccidentAcrident.dll error

When Windows starts it loads a bunch of system DDLs and will throw an error if there was an issue with any one of them.  The OccidentAcrident.dll startup error, as the name implies, is an error you’ll face on startup. The most common way you’ll receive this error is after upgrading to Windows 10 or installing some program.

How to fix the OccidentAcrident.dll startup error

Solution 1 — Use Autoruns

As mentioned above, this is a startup problem. That’s why this program is immensely useful. It lets you look at what processes run at startup, when built-in Windows programs start, and how they are configured. It is basically a one-stop shop for anything related to Windows startup. We’ll see how we can use Autoruns to fix this problem.

Use Autoruns to delete entries of missing files

  1. You should create a system restore point because we are treading dangerous grounds. If you don’t know how to do it, you can follow our tutorial.
  2. Download the Autoruns program.
  3. Autoruns will download in the form of a zip.
  4. If you have 32-bit Windows, you should right-click on Autoruns.exe, or you should right click on Autoruns64.exe if you have a 64-bit Windows. In both cases, click Run as an administrator after right-clicking on the file.Run Autoruns as an administrator
  5. After Autoruns opens, try to locate entries with a yellow color and an Image Path that begins with File not found. This signifies that there is a rule that specifies running a certain program at startup but the file that is supposed to be executed is not found; those files could contribute and relate to the error you are facing.
  6. On finding any such entry, right-click on it and choose delete from the drop-down menu.Delete File not found entries
  7. Double check that you’ve deleted all the entries and then restart the computer, and you should be good to go.

Use Autorun to disable third-party entries

This is a tedious method that will involve you restarting your computer a dozen of times so we recommend that you try all the other options before this one.

  1. Start Autoruns with administrator privilege.
  2. Examine whether the publisher of an entry is Microsoft Corporation or not.
  3. If it has a third party publisher, uncheck the entry and restart your computer.Uncheck third party entries
  4. If the problem still persists, that means that application wasn’t the problem, and you should enable it again.
  5. Repeat step 1-4 for all the third party entries one by one. If you didn’t face the error after disabling a certain program, most likely, it is the culprit.

Solution 2 — Use System Restore

If you’ve started getting this error recently, you can restore your computer to a prior state using System Restore. The only hurdle would be that there must be a restore point dated before the error that you can go back to. Thankfully Windows creates restore points when it updates your system, and many programs, like Office and 3ds Max, automatically create restore points during their installation. Follow these steps to restore your computer:

  1. Right-click on the Start button and select Control Panel.
  2. Open Recovery by searching for it in Control Panel.
  3. Click on Open System Restore.Open System Restore
  4. Click Next and you’ll see a list of restore points. The best restore point would be one that is recent and predates the error.
  5. Select the restore point and click next. Windows will show you a list of hard drives that will be affected. Click Finish to begin the restoration process.System Restore

Solution 3 — Use Windows installation media

Using an installation media gives you two new ways to recover your system. Before we start, naturally, you must have either a disc or USB with Windows’ installation files on it. If you don’t have it, you can easily create it by following the instructions in this article.

  3. Starting the installation, choose the language you prefer and click Next.
  4. Choose Repair your computer, then click Troubleshoot.
  5. Finally, select  Reset this PC. This should reset your PC and solve your problem.
