um diamond... im not sure that's entirely accurate... *goes and pulls up code*
CRegistryManager reg;
reg.GetString("Software\\DMEN\\FS2UTIL", "InstalledAt",
"C:\\Program Files\\kazan", CStemp, 1024); // defaults to the default install path
InstallPath = CStemp;
apstring Suns = InstallPath + "\\Suns.lst";
apstring Nebs = InstallPath + "\\Nebulae.lst";
ifstream Sin(Suns.c_str(), ios::nocreate);
ifstream Nin(Nebs.c_str(), ios::nocreate);
where ever the string value named InstalledAt in registry key HKEY_LOCAL_MACHINE\Software\DMEN\FS2UTIL points at is where they need to be
*considers updatting this util as well*
