I can't start mining, miner just closed after 2 seconds, nothing is written in console. How can I find the problem?

This miner: https://github.com/jagaricoin-project/jagaricoinR/releases/download/v1.0.1.0/cpuminer-2.6.0-src_R24_slow_x64.zip
Try: Intel Corei5 Windows 7 and Celeron G3930 Windows 10

yep you need to provide us a way to swap the old coins with the new ones.
