MalwareBytes Stopped Loading, Missing DLL Function

Recommended Posts

Got a popup a few minutes ago telling me real-time protection was disabled, at the same time I noticed the MB3 icon had gone from the system tray.

When I try to restart it I now get this error message:

"The procedure entry point ?setSceneGraphBackend@QuickWindow@@SAXW4GraphicsApi@QSGRenderInterface@@@Z - could not ne located in the dynamic link library Qt5Quick.dll"

Presumably MB3 has updated itself to now need a function in a QT5 DLL that isn't there or

This is likely due to an issue with the recent update which has been having problems during installation occasionally for some users.  Generally reinstalling Malwarebytes fixes it so please download and install Malwarebytes from here and then try to open it, then go to Settings>Application and click on the Install Application Updates button to make sure that you get all of the latest components.

Once that's done, assuming it is working, go to Settings>About and verify that your Malwarebytes and component package versions match those shown below:

Thanks for the instructions, which (as you expected) seemed to work fine and MB is now back up and running.

I did consider a simple re-install but I kind of get suspicious when things just 'stop working' like this, sadly my experience over the years with MB's updates regularly breaking (typically some modes like real-time protection simply ceasing to enable which Ive suffered three times so far) should have taught me that's going to solve it every time.

You're welcome, yes I don't know what's going on with this most recent update/build, but this shouldn't have happened and I'm convinced based on the number of users affected which all started showing up this past Friday afternoon, that there is something going on causing it, likely related to the particular update server they are contacting and maybe it has a corrupt copy of the installation files or something.  I don't know, but I have reported it to the team for investigation so hopefully they'll figure it out and get it corrected before too many more users are impacted by this issue when trying to update.
