Certain apps crash randomly at the address within the web root injection DLL (WRDll.x86.dll). I was able to capture the following crash dump from one of the apps. Hard to reproduce, unclear why it happens. Maybe your dev team can look into this. WRDll.x86.dll version 1.1.0.226.

It’s best to do a reinstall as I posted above as it only takes a few minutes!

 

Look here to see the version number:

 

 

 

Or hover over the Webroot Tray Icon:

Hello @fmike7 there is no such version! The current release for PC is v9.0.29.52

 

So please try a clean reinstall and after WRDll.x86.dll version will be 1.1.0.227

 

Please follow the steps closely!

  • Make sure you have a copy of your 20 Character Alphanumeric Keycode! Example: SA69-AAAA-A783-DE78-XXXX
  • Be sure you add your Keycode to your Online Console: Webroot SecureAnywhere Online Console
  • KEEP the computer online for Uninstall and Reinstall to make sure it works correctly
  • Download a Copy Here (Best Buy Geek Squad Subscription PC users click HERE) Let us know if it is the Mac version you need
  • Uninstall WSA and Reboot
  • Look to see if this folder is gone: C:\ProgramData\WRData and if it’s there delete it. (Hidden Area)
  • Install with the new installer, enter your Keycode
  • Let it finish it's install scan
  • Reboot once again
  • DO NOT import any old settings as you can set it up as you like once it's done

Please let us know if that resolves your issue?

Thanks,

For some reason, 9.6.14 is what is shows in Add/Remove Programs in Windows.

Does it automatically update WRDll.x86.dll when you release new versions? This particular application that crashed was 32 bit Windows service. I will see if this crash happens again after the update to the most recent version.
