Start Update or installation fails on Vista.

When you try to run an update after installing Lavasoft Anti-Virus Helix on Windows Vista, by selecting Start update in Lavasoft Anti-Virus Helix main window, nothing is happening.

This problem occurs if you previously ran Norton Removal Tool on the computer. This removed an important system variable, Common AppData, and so Lavasoft Anti-Virus Helix places its application directory in C:\Windows\.

In other cases the installation is apparently accomplished by Lavasoft Anti-Virus Helix, after click on Finish the Setup can crash. But neither the Lavasoft Anti-Virus Helix program symbol appears on the Desktop also no files are in the installation directory.

In order to solve this problems, you need to edit the registry.

Go to Start -> Run..., type the command regedit and press OK. Navigate to and open the following key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\Shell Folders

Right click and select Edit for this value.

    Common AppData

Change the value to:
