Sharpcap depends on the Microsoft .NET
Framework, which you'll need to install before trying to run SharpCap.
If you have Windows Vista or Windows 7, you will already have this
installed. On Windows XP, you may need to install it from this link.
Note that the installers for some older versions below this point have
been removed and the links will not work. The most recent release of each version should still be
available in the old build archive.
