AccelerometerSt.exe error (0xc000007b) on start up after HP update to driver

[ElaineK1809]

Update HistoryStart up

I got an update for the 3D guarddrive yesterday. Since the update I get AccelerometerST.exe error. I have tried uninstalling the 3D Driveguard and reinstalling as recommended on other threads. It hasn't helped. I think when uninstalling 3d via uninstall on control panel it isn't completely uninstalling because when I reinstall it says files already there.  Advice on how to tackle much appreciated.

Hi,

Try the following.

Open windows Control Panel, open Programs and Features, right click the entry for HP 3D DriveGuard and select Uninstall.

When this has completed, restart the notebook.

Download the version of HP 3D DriveGuard on the following link and save it to your Downloads folder.

http://ftp.hp.com/pub/softpaq/sp81001-81500/sp81142.exe

Download and install the x64 version of 7-Zip on the link below.

http://www.7-zip.org/

When you've installed 7-Zip, open your Downloads folder, right click on the sp81142 package, select 7-Zip, select extract files and then click Ok.

Cut this newly extracted folder and paste it on your Desktop so it's easy to find.

When done, hold down the Windows key and press R

Into the Run window, type devmgmt.msc and hit enter.

In Device Manager, expand System devices, right click the HP Mobile Data Protection Sensor entry and select 'Update Driver Software'.

In the following window, select 'Browser my computer for driver software' and then select 'Let me pick from a list of device drivers on my computer'.

In the next window, click the 'Have Disk' button and then browse to the extracted  sp81142 folder you pasted on your Desktop.

Browse into the sub-folder InstallFiles, open the folder Win10, left click on the file accelerometer to highlight it and then click Open.

Click on 'Ok' and then click 'Next' and wait for the driver to install.

When done, click 'Close' and then click 'Yes' to restart the notebook.

Hi

I followed your instructions and the error message on start up no longer appears.

After the drivers had installed I got the message saying they had been successfully updated. The only thing is I can't see the HP 3D Driveguard program in control panel now ... shouldn't it be there?

Thanks for your assistance.

Hi,

You're welcome

Using this method doesn't create an entry in Winows control panel for HP 3D DriveGuard, however, as long as the driver has installed, the hard drive protection will work as usual.

Hi 

I only have limited skills so I wasn't sure if it should be there or not. 

Thanks for your help.
