Does not work with OS11 and higher

Note: Oligo 7 works with the newest Windows operating systems and Mac OS 11 (tested on Big Sur).  Oligo 7 downloads contain the Manual & Tutorial. Oligo on the Mac with systems 10.10.5 and above needs to use the latest Java version (download from here) in order to work smoothly. Oligo for Mac may also work on the newest Java for Mac OS from Oracle, but in order to make it work you need to download this special OLIGO version and start Oligo for the first time with Control-click the Oligo icon, then choose Open from the shortcut menu. If the newest Java version doesn't work, you may download the working version from our site: Java_Oligo.zip uncompress it and read the instructions.
To receive the full version you need to purchase the license number. Click on the "Ordering" link at the top of this page for the pricing info.
The summary of Oligo 7 improvements is given here.
