To use my perl programs in windows you can either take the .exe files from the downloads page or you can install activeperl. The exe files seem to have problem that their load time is several seconds, i.e. when you start them it takes several seconds before they even start doing anything. Perl versions are much faster.
To install activeperl go to www.activeperl.org site and download Standard Distribution (click download activeperl in right and then select ActivePerl download (note that email etc are all optional) and then select Windows (x86) MSI version).
When installing it select default paths (C:\perl) and ask it to add itself to the path, and associate itself to the .pl extension.
Next unpack files from perlib directory inside to modules-<version>.zip to c:\perl\site\lib, and files from bin directory inside genericbins-<version>.zip and specificbins-<version>.zip to c:\perl\site\bin.
To allow easy use of those, add c:\perl\site\bin to path. This can be done by starting control panel -> system -> advanced -> environment variables -> Path in the system variables section -> edit -> add "c:\perl\site\bin;" to beginning of the list just before "c:\perl\bin".
If some of the perl programs says that some module cannot be found for example "Math/Quaternion.pm" install missing packages by saying "ppm install Math::Quaternion".
To install CPAN stuff you might need make, i.e. download nmake15.exe from https://support.microsoft.com/default.aspx?scid=kb;en-us;Q132084 page run it to extract it, and then copy nmake.exe and nmake.err to c:\perl\bin.
To install Math::Vector, you need to use "cpan -fi Math::Vector", and after it installed the Math::Vector file you need to move it from c:\perl\site\lib\Vector.pm to c:\perl\site\lib\Math\Vector.pm (the installer installs it in wrong place).
If you want to use trngraph and other utilities which use GD graphics, install GD libraries by saying: "ppm install https://theoryx5.uwinnipeg.ca/ppms/GD.ppd"
