| A. The 16-bit components of the InstallShield software used for installation of Crossing the Mountains may exhibit this problem on operating systems where the creation of short file names has been disabled (e.g. by setting the NtfsDisable8dot3NameCreation registry value to 1). This problem may be solved by moving the setup file to a location which does not use long names in its path components (e.g. the root of drive C) and running it from there. If this does not solve the problem, a change to a registry value is required.
