keeping only the last 4-digits for verification purposes.

it will end your secure (TLS) connection to our Server,
taking you back to a non-secure page.
Once your payment has been processed, we will display a Receipt,
which you should print out.
If you have paid by a Credit-Card and the transaction has
cleared smoothly, we will generate your Licenses and Activation-Codes
immediately and display them on a final page.
Very definitely print out this page.
At this point, the transaction is complete.
Click on the "Finish" button.

After you have purchased your Licenses,

and copy the program packages down to your computer.
Normally, you can download the compressed files, and your Browser will
expand them automatically.
If you have trouble with this, you can download the uncompressed
You must run the program package to extract the program and to
activate it, using your License Number and Activation Code.
This is why you printed out that final page.
If the Browser expansion of the compressed file has not set the
package as executable, you will have to do this by-hand.
On Unix or MacOSX:
chmod +x program.prgpkg
Executing this package file will prompt you for four pieces of
The first is your name, and the second is your Customer-Number with us.
Then, it will prompt you for the License-Number from your purchase.
Finally, it will prompt you for the Activation-Code, printed on the
License-Page from your purchase.
After you enter all this correctly, it will produce a
program.exe file, and you are all set.
You can copy this whereever you wish it to reside
(/usr/local/bin, for example).
On Unix, you may not like having the "exe"
file-extension. You do not need to keep it.
At HEPArts, we keep the extension on the file
but add a symbolic link to it in addition:
program@ -> program.exe
We find it advantageous to keep the file-extension for doing searches.
