https://community.graphisoft.com/t5/Installation-update/Code-Meter-Error-Code-501/m-p/264715#M27551 I am trying to download the license for the code meter to see if that will solve the problem but I am getting an alert about the GSROOT.dll file. Can anyone tell me if this file is a risk?

It then asks if I want to start in demo mode or quit.<BR /> It acts as if there is no code meter installed but prior to today I haven't had any issues. Any help??</T></DIV> Wed, 29 Apr 2015 12:17:45 GMT https://community.graphisoft.com/t5/Installation-update/Code-Meter-Error-Code-501/m-p/264714#M27550 JPL_DESIGN_GUY 2015-04-29T12:17:45Z https://community.graphisoft.com/t5/Installation-update/Code-Meter-Error-Code-501/m-p/264715#M27551 I am trying to download the license for the code meter to see if that will solve the problem but I am getting an alert about the GSROOT.dll file.
