With the 1.10.14 release and later, you must also have the
.NET Framework 1.1 installed on your PC. You may already have this installed as it is a part of Windows Update. To check whether or not you have it installed, please see
this article.
*Note: There is also a Microsoft .NET Framework 2.0 for your PC. As it seems this is a later version, it is actually a completely separate installation. Logbook Pro requires that you specifically install version 1.1 of the .NET Framework. You can also install 2.0 as our later applications will use this, both can be installed on the same PC, they are again separate runtime engines altogether.
