Here is the solution for this problem.
The text file is the license you need to run the personal version.
There is no "personal edition construct 2" to download. I think that if you put the text file in your "Documents" Construct 2 reads the license automatically. If this does not work, this is what you do:
1. Put the text file somewhere where you remember where it is.

2. Press the i in the top right corner inside C2.

3. I already have the personal edition installed but where it says "view license" it should say something like "open license".

4. Go to where you saved the license, double click the license restart Construct 2 and you're done :) No problem.
