As a couple of users have reported that they managed to resolve the issue by installing every pending update available for their Windows version. This is further evidence that the issue can also be caused by a driver incompatibility introduced with a Windows update.

  3. Once you know exactly what updates are currently pending, follow the on-screen prompts to install every pending update.
    Note: If you’re prompted to restart before every pending update is installed DO It, but make sure to return to the same screen and continue with the installation of the rest of the updates until you’re up to date.
  4. When every pending update is installed, restart your computer and see if the issue is resolved once the next startup sequence is complete.

If the same accelerometerdll.DLL not found error is still occurring, move down to the next method below.

Method 4: Perform a system restore

If none of the methods above have allowed you to resolve the issue conventionally, it’s very likely that the issue is occurring due to some kind of system file corruption. In this case, you should be able to resolve the issue by using a system restore point to bring your computer to a previous point in time where this particular issue was not occurring.

Of course, this method will only work as long as you have a restore point that works for you and enables you to return your machine state to a healthy point. However, be warned that this method will also undo any changes that you made since the restore point was created. This means that all apps, user preferences and other changes to your system will also be reversed.

If you have decided to perform a system restore in order to resolve the accelerometerdll.DLL not found error, here’s what you need to do:

  1. Press Windows key + R to open up a Run dialog box. Next, type ‘rstrui’ inside the text box and press Enter to open up the System Restore utility. If you’re prompted by the UAC (User Account Control) prompt, click Yes to grant administrative privileges.
    Opening the System Restore wizard via Run box
  2. Once you’re inside the System Restore wizard, start by clicking Next to advance to the next menu.
    Getting past the initial screen of System Restore
  3. Once you get to the next screen, start by checking the box associated with Show more restore points. Next, check the dates associated with each restore point and decide which one you’re going to use to restore your computer to a healthy state. When you’ve decided, select the appropriate restore point and click Next once again.
    Enable Show more restore points box and click Next
    Enable Show more restore points box and click Next
  4. Next, click on Finish to start the system restoring process. Immediately after you hit this button, your computer will restart and the older PC state will be mounted at the next system startup.
