Hi. When I redeemed the license code, a text file was created. I expected a multi-step process where the construct 2 program was downloaded. That did not happen. The only outcome that I can see was the text file creation with the license data. I am SURE this is user error but I don't know what to do. This will probably be the most ignorant question you answer on the forum, so thank you for your time in answering.
The license file just unlocks the full functions of the free version, so you will need to download that first.
Follow the instructions from the manual starting from HERE.
After downloading, follow the 'Install Construct 2' and 'Installing a License' manual entries, and you should be good to go.
