You can buy permanent copies of our software online via 'Digital River'. Each costs $12.00 .
After your order is complete, you'll be able to download immediately! Download SiliconK521.exe, or SpectrumShiftPaint_311.exe into a temp directory on your machine and then run it. This will launch a setup program.
These programs run on Windows 7, 8 and 10.
Alternatively, you can order by mailing a check and I will mail the CD(s) back to you. Each title is on a different CD, so if you want more than one, you will have to purchase multiple CD's. Each CD costs $12.00 . There is no charge for shipping to addresses inside the U.S.A. Enclose an additional $3.00 per CD to cover postage if your address is outside the U.S.A.
