If you press "back" during the installation and then "next" again, then the checkmarks will be installed in the opposite direction.

Thank you for the feedback. Pleas specify which installer you're referring to, so we can check it.

At all the installation program.
For example:

aimp.ru aimp_4.12.1880.exe - If you press "Back" and then "Next", the check marks are returned.

piriform.com ccsetup531.exe - If you change the language, the check marks are returned.

I'm not sure I understand what you mean. An animated screenshot of AIMP is attached below. Going back and forward again keeps the checkboxes unchecked.

If you meant something else, please explain or provide a screenshot. Thanks.

Thank You!)
