I’ve been struggling to install the beast that is Clearcase 7.1.1 on a proof of concept server. In this case the server is a Solaris 10 64bit install running on VMware Fusion 3. One of the initial mistakes I made was to try and run the installation from a network mount. DON’T. Solaris must block the execution of code on some types of removable drives, which in this case was a VMWare Fusion shared folder.
