Paralog / NMU

Information about ATLAS and Paralog (needs to be bought separately)

We are currently investigating problems with Windows 11 and Paralog which is most likely a problem on the manufacturers USB driver which is out of our hands. Please understand unless we finished investigating this you should not use Windows 11 and Paralog. We expect more answers beginning January 2022. Sorry for the inconvenience but as said: Out of our hands. 

You can download Paralog files here Paralog 8.7.7
