Can't install to root?

See simple script below: NSIS doesn't let me install into the root directory, the "Install" button is grayed out until I enter a different path?!

Reason why I need this: I'd like to make an installer that does actually build an install script for making a backup of a selected directory and compiles it- and I'd sure like to backup the root drive 🙂

Name "Backup"
OutFile "BackupGen.exe"
Caption "Create Backup Script"

; Use Show to let user see directories that are scanned
ShowInstDetails Show

;ComponentText "Check he drives where you want the installer to scan for files." "" "Select drives to scan:"

InstallDir "C:\"
DirText "Select wich directory you want to backup:"

Section "Create Backup Script"
StrCpy $9 $INSTDIR
Ca;...
SectionEnd

You'll need to change the InstallDir string in:
InstallDir "C:\ " ; So with a space behind C:\!

The default logic is to not allow installs into root directories, primarily for safety reasons. Disabling this would be fairly easy but would require a reinstall. Perhaps I should add a config item to let you change that, but I dunno...

P.S. for now, if you don't need the user to be able to select it, you can just not use $INSTDIR, and just use a variable instead...

Thanks!

In the new versions (newer than 1.8b2) the option AllowRootDirInstall is added. That's what you need, I think!

I've seen that, THANKS!
