I have found solution. Here it is:

nsCOMPtr serviceManager;
NS_GetServiceManager(getter_AddRefs(serviceManager ));

nsCOMPtr directoryService;
serviceManager->GetServiceByContractID("@mozilla.org/file/directory_service;1",
NS_GET_IID(nsIDirectoryServiceProvider),
getter_AddRefs(directoryService));

nsCOMPtr properties =
do_QueryInterface(directoryService);

nsCOMPtr userMimeTypesFile;
properties->Get("UMimTyp", NS_GET_IID(nsIFile),
getter_AddRefs(userMimeTypesFile));

nsEmbedCString nativePath;
userMimeTypesFile->GetNativePath(nativePath);

With best regards,

Thanks Edward,

your post solved my question: How do I retrieve components installation
path?

void setLibraryLocation(void)
{
nsCOMPtr sm;
nsresult rv = NS_GetServiceManager(getter_AddRefs(sm));
if(!NS_FAILED(rv))
{
nsCOMPtr dirserv;

sm->GetServiceByContractID("@mozilla.org/file/directory_service;1",
NS_GET_IID(nsIDirectoryService), getter_AddRefs(dirserv));
nsCOMPtr props=do_QueryInterface(dirserv);
nsCOMPtr aPath;
props->Get("ComsD",NS_GET_IID(nsIFile),getter_AddRefs(aPath));
nsEmbedCString libloc;
aPath->GetNativePath(libloc);
#ifdef DO_DEBUG
alert(libloc.get());
#endif
libLocation = (char*)malloc(sizeof(char)*(libloc.Length()+13));
strcpy(libLocation,libloc.get());
char* slashpos=strchr(libLocation,'/');
if(slashpos && strchr(slashpos+1,'/'))
strcat(libLocation,"/");
else
strcat(libLocation,"\\");
strcat(libLocation,"printlib.so");
};
}
