What is the correct -a for cnv8_dbl?
teamredminer.exe -a cnv8_dbl not work at windows it close the window at startup.
Can you provide your full cmd line? If you have the miner working fine with cnr or cnv8, you should be able to set "cnv8_dbl" as algo and change the pool/wallet/password, and things should work.
Here we go:
teamredminer.exe -a cnv8_dbl -o stratum+tcp://eu.XCA.cryptopool.space:7777 -u XCA... -p xxx --cn_config 16+14,16+14,16+14,16+14 --watchdog_script=watchdog.bat
Are you sure you're running the latest 0.4.2 version? The thing is your cmd line works fine for me, only thing I replaced was the wallet.
If you're running this from a .bat file and the window closes so you don't see any output, can you add a line with "pause" at the end of the .bat, then paste the output here?
