SubSectionend

Function .onSelChange

!insertmacro StartRadioButtons $1

Did you initialise $1 in .onInit?

Hi have only this..

;Installer Functions
Function .onInit
!insertmacro MUI_LANGDLL_DISPLAY
FunctionEnd


How can do it?
THanks for your help.
I'm real beginner.. :-(

Add this line in .onInit:

StrCpy $1  ${com1}

And remove optional switch (/o) for COM1 section:

Section "=> COM1" com1

I have already tested this
(from EXAMPLE
StrCpy $1 ${g1o1} ; Group 1 - Option 1 is selected by default)

but the result is the same: CAN SWITCH from COM1 and COM2 but cannot UNSELECT BOTH if Select it making error.
I want to DESELECT SUBSECTION (for example if i remember AFTER that have no COM port but only USB port)
Now "SubSection /e $(nce)" is in GRAY WITH FLAG and cannot deselect :-(

The RadioButton macro doesn't do that. It doesn't allow the user to select no section at all, but only one section, no more, no less. There were some threads in the forum with possible solutions. I couldn't find them with a quick search, maybe you'd have more luck. You might want to search the Wiki too.

Maybe this will help (I'm not sure):

See here. I think you have special case for 2 sections.
