About Lines95 version 2.0
If you have version 2.0 installed that may be
small problem with Registry.
To prevent it you must delete old information
from registry by

Run regedit find keys
\HKEY_KEY_CURRENT_USER\Software\NPS\Lines95
\HKEY_LOCAL_MACHINE\Software\NPS\Lines95
and delete it.

Sincerely yours
