Re: create or join network button doesn't work.

  Sorry for that.  What you can do is manually remove these locations:

1. Navigate to C:\Program Files; Locate LogMeIn Hamachi folder to delete
2. XP OS: C:\Documents and Settings\AllUsers\LocalSettings\Appdata:  Delete LogMeIn Hamachi folder
3. Remove Registry Keys: 
   1. HKEY_LOCAL_MACHINE\SOFTWARE\LogMeIn Hamachi
   2. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Hamachi2Svc
   3. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hamachi
