Entry Point Not Found on Vista

Avast Free Antivirus / Premium Security
1

Hello

I have just installed the latest version of Avast on my Windows Vista PC.

I am getting an error message “The procedure entry point _tskChangeExcludeHash@16 could not be located in the dynamic link library ashTask.dll” at the end of the install.

Can anyone tell me what I need to do to sort this please?

Thanks

Roy

Hi

Free version of Avast - this is an upgrade from an existing version of Avast (which worked) to the latest version taken from the website. I cannot tell you more as the UI refuses to open and just give the error message.

32 bit Windows Vista Home Premium SP2

Zone Alarm Firewall

No other security software

Then:

  1. Download Avast Free Antivirus: https://files.avast.com/iavs9x/avast_free_antivirus_setup_offline.exe
  2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions…!!)
  3. Reinstall Avast with the downloaded installer from point 1.
  4. Reboot.
