Problem choosing custom path for unistaller

Hi, I would like to write a custom path for writing my uninstaller but the installer return an error when creating the uninstaller.
The path is outside the install directory.
Do we necessarily have to write the uninstaller inside the install directory ?
Thanking you

The installer does not care where you put it but the directory has to exist before you call WriteUninstaller.

Don't forget that $instdir in the uninstaller is the directory the uninstaller is in.
