Unit Conversion was written in Visual BASIC, using Microsoft Visual Studio© 2008. It reqires that the .NET framework be installed. The installation package was also created with Visual Studio... It copies the following files to the selected installation directory;
When it is launched for the first time by a user, the Unit Conversion program copies the unit_data.udt and license.txt files to
the working subdirectory selected by that user to house his or her data. The license.dat file is also created in the user
data directory during the first session; it contains the user's name and, if the program has been registered, his or
her registration code.
Unit conversion creates a set of Registry keys grouped in HKCU\Software\VB and VBA Program Settings\Convertit. This group of keys contains
information such as the location of the data directory for the current user and various settings.
Unit conversion can be uninstalled from the Control Panel. Since the registry keys discussed above are created by the program
during operation rather than during the installation process, they must be manually removed using Regedit. They can also
be safely left in place, as they do not impact the operation of any other Windows programs or components.
Similarly, since the working directory is created by the program for each user, rather than by the installer, it must be manually deleted. It can
also be safely left in place, as it takes up very little disk space. Note that if a new version of Unit Conversion is to be
installed, both the registry keys and working directory must be left in place so that settings, registration information and user defined
unit data will be available in the new version.
