Auto-opening wbv logs in Vista/Win7

Some people get an error when double clicking to open a wbv log file. There is a quick fix for this problem. Open the registry (if you don't know how to do this you shouldn't be messing around in there anyway) and go to this path: HKEY_USERS\S-1-5-21-3048228873-3804879394-597272701-500_Classes\wbv_auto_file\shell\open\command

The key at this path will be:
"C:\Program Files\WinBolo\Log Viewer.exe" "%1"

Remove the quotes around the %1 so it looks like this:
"C:\Program Files\WinBolo\Log Viewer.exe" %1

That's it! Big thanks to Min for figuring it out.
