Hello,
I just had a quick look at Ketarin and I like the idea behind this application.
It does not need to be installed.
It does not scan the computer for installed software.
It does not require a database that manages the available version.
I tried to manually add the Download URL for CCleaner.
I wanted to add the URL not from Filehippo, because I need to understand the technique behind Ketarin.
What I miss here is a Wiki where you get a "tutorial" for many applications.
Like the tutorial that you offer but for other applications, like CCleaner or Total Commander.
In the forum I did not find anything for those applications (just doing a quick search).
So, please consider such a Wiki where you publish tutorials for many applications.
And maybe you offer templates to download.
Greetings
OLLI
