Aiolos needs two registry variables to find its directories. One of them should point to the data and one to the executables.
The one pointing to the root of the data is AppMainDir, and the one that points to the root of the executables are ExeRoot.
The system first looks for these variables in HKEY_CU\SOFTWARE\Vitec\Aiolos\Setup and if they are found their values are used, if not found it looks in HKEY_LM\SOFTWARE\Vitec\Aiolos\Setup and uses the values found there. This mechanism is intended for having multiple installations on the same machine using different databases depending on how you log in.
A sample of a registry file to set up these variables to the two directories mentioned above is;
REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Vitec\Aiolos\Setup]
"AppMainDir"="X:\\Aiolos\\demo"
"ExeRoot"="C:\\Program\\Aiolos"
