Salut mes canards
Voilà une méthode pour installer dreamfall avec moins de 7 Go sur C:
"Go to Start -> Run:
Type RegEdit
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion
On the right side is something called: ProgramFilesDir
*Write down the current path of the ProgramFilesDir, you'll need to change it back after install*
Change this value to a drive that contains 7+ gigs of space
Install Dreamfall
*Go back into the Registry, to ProgramFilesDir, and change it's value back to what it originally was.*
Don’t mess up your registry by doing anything else."
