"" is nothing. " " is a space.

Yes. The point is:
When using installoptions, you (I) write:
WriteIniStr x.ini "Field 1" State ""
But installoptions writes -> State=" "
If ReadIniStr reads a space, why don't read '" "' ?
(don't answer this. It's just a cry)
I'm writing this just as one thing to remember.

So InstallOptions supposedly writes a space " " but when you read from it with ReadINIStr, it's ""?
Perhaps InstallOptions puts a null-escape (\0) character there which usually looks like whitespace in a text editor (in Notepad2 however it comes out as NUL).
