Read a reg key --- write a reg key
Hi there,
this was maybe asked before, but if so, I didn´t find it !
I want to read out a registry key. If it exists I want the installer to do nothing.
If it doesn´t exist I want the program to write 3 new keys.
I found all the commands in the readme, but don´t know how to put them in a right order. so please help me with that and post a complete sequence, cause I´m a totally newb in coding !

ReadRegStr $R0 HKLM "Software\myApp" shit ;Reads the Value of Shit into the Var $R0
StrCmp $R0 "VALUE" done write ;If $R0 is like "VALUE" it goes to done, if it has another value or isn't there it goes to write
write:
WriteRegStr HKLM "Software\myApp" "shit" "VALUE"
WriteRegStr HKLM "Software\myApp" "shit" "VALUE1"
WriteRegStr HKLM "Software\myApp" "shit" "VALUE2"
done:
this code was written Online, but it should work

But when i´ve compiled the program it shows an error:

ReadRegStr $R0 HKLM "Software\HKS Informatik GmbH\Kosy-KK" InstallVersion

You have to call your function key in another function or section, else it isn't referenced and so the Compiler will leave it out
If you have a main section which is installed anyway, put there the Line "call key"
the other option is to don't put the code in a Function but in the Section where you need it.
If you write a function you ever have to call it
Hope this helps to understand
