I have a program that I use with my 3Dart program. It installs with a self-executing .exe file.-that bit runs with no issue. When I click on the .exe file in the final folder (for the real program install) nothing happens. I use Win7 64 bit system & use the free copy of Avast(version is 11.2.2261) I've tried disabling it for the installs-no progress. I actually have to totally uninstall Avast so that I can do my program updates with that file.The program is called Reality & is a safe program. I can't figure out the interface on this version of Avast so I've no clue if I missed a setting or what. Is there a way that anyone can be of help? It'd be very much appreciated:) Thanks.
