My suggestion is to put the NON installable portable edition back online and remove the paid "technician" version. This was a completely horrable idea on your part and is just a way to increase your revinue streams. The only thing that set you ahead of the game was that you had a free portable edition. Why would anyone want to install your product say over Malwarebytes? If I have to install something might as well be that.
I also suggest that everyone boycott this product until they bring back the free NON installable portable edition. If they want to have a seperate advanced version that technicians can pay for thats fine, but a free truely portable version needs to be made available asap.
