I'm trying to install the 14.0 beta (composer_xe_2013_sp1.0.051) just for me (not as root, not using sudo). Unfortunately, I deleted an earlier install by removing the files by hand. Evidently, there is a secret stash of information that the installer consults, because now when I run ./install.sh, the installer thinks that the compiler is already installed, and refuses to install it again. How can I force a re-install?
