Hi all and Happy New Year

The question is this.

Im making a community game mod installer ,and file xyz.txt is not found in InstallDir i like to disable/hide components page and if file xyz.txt is found i like components page to be shown.

If that is not possible ,how can i disable user to select some option components depending if that file is found or not?

Thanks in advance ,and sorry for mine bad english

If you don't want to skip the page (maybe a better idea...)

code:


!include LogicLib.nsh

!include Sections.nsh



Section "My Section" MySection1

SectionEnd



...

${Unless} ${FileExists} $INSTDIR\xyz.txt

SectionSetFlags ${MySection1} ${SF_RO}

...

${EndUnless}
