Instacal 6.51 works on windows 11 but it does not recognize any boards or in this case the USB 1608G. The only way we get it to work properly is if we download windows 10, download instacal then update it to windows 11 but we are trying to avoid using that due to windows cutting off support for windows 10 in 2025.
Yes we downloaded the new instacal 6.72 and it does recognize the boards but the program we try to run on it doesnt support it.
