[@Saamwoon] They remove the installation folder dialog because they want to force install the program into an insecure location where those normally restricted in a standard user account, because the computer is not theirs and need an administrators approval to install software, can write. They prevent others that want to install the program properly into a secured location against non-elevated writes or onto another drive letter cannot install softorbits programs where and how they want/need to. It is normally possible to reverse this situation IF you are reasonably proficient with windows using FREE Innoextractor program and a copy of Inno installer package compiler one can extract the contents of the softorbits installer and edit the install_script.iss to not disable the lines:
DisableDirPage=yes
DisableProgramGroupPage=yes
either by ; commenting them out or changing the values to either “auto” or “no”
and probably commenting out:
PrivilegesRequired=lowest
and recompiling the .iss script.
