JamesCourt 4 Report post Posted September 17, 2017 These are the instructions to installl, run and register Camtasia 9 for PC. Unpack, install. Remove all techsmith blocked entries from the hosts file. If you've previously blocked this product hosts, your hosts file should contain the following entries - remove them. 127.0.0.1 www.techsmith.com 127.0.0.1 activation.cloud.techsmith.com 127.0.0.1 oscount.techsmith.com 127.0.0.1 updater.techsmith.com 127.0.0.1 camtasiatudi.techsmith.com 127.0.0.1 tsccloud.cloudapp.net 127.0.0.1 assets.cloud.techsmith.com NOTE! Without removing the entries, the registration will not be completed. Completely block the program executables in your firewall: <install dir>\CamtasiaStudio.exe <install dir>\CamRecorder.exe Use our Keygen to register the application. However, I do not understand what the hosts file is or how to go about doing the blocking. I apologise for my ignorance, but can someone explain it in simple terms and a bit more detail. I appreciate your help James Share this post Link to post Share on other sites
