This will check if 7-zip & Notepad++ are installed, and if they are selected or un-selected, it will install or un-install them.
My problem is that, if for example I select 7-zip and install it, if I then un-select it and click OK, it will not un-install it.
I have to close the form, re-open it, and then if I un-select 7-zip and click OK it will un-install it.
It’s like, after each operation, the form must be closed and then re-opened, for it to work again.
Is there a way I can avoid this?
Thanks
