#321692 Avsim library is working fine for me. But it looks like ASRC may have been one of the files that was lost after the avsim site was hacked. And since the original ASRC site is down now, VRC will probably be your only option, unless someone knows of somewhere that ASRC is stashed.

#335601 ASRC was an excellent radar client in its day but very old school, my advice would be download VRC and Euroscope and make an informed choice on which one you would like to use.
