Problem with manual update Avast 5.0.507

How can I solve this error???

“Can’t install VPS update. Please, report following error codes: Ver. 5.0.507 SI: 0x00000002 ST: 0xFFFFFFFE LE: 0x00000000.”

I’ve win vista home basic, and previously I had installed avast ver 4.8… and never had problem with manual update in this previous version, and now yes…

Please help me to solve this.

First you should update to the latest version. (See my sig!)

I suggest an installation from the scratch:

  1. Download the latest version of avast! Uninstall Utility and save it.
  2. Download the latest avast! version and save it.
  3. Uninstall avast from Control Panel (if possible). If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after that.
  4. Run the avast! Uninstall Utility saved on 1. If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after you’ve run it.
  5. Install avast! using the setup saved on 2. Boot.
  6. Register your free copy or add the license key for Pro.
  7. Check and post the results.
