Resolution: If RV is installed on a 64-bit machine, a "64" sub directory <RV_Home>/lib/64 is created where you can find the 64-bit version of the RV libraries. The error occurs if you use <RV_Home>/lib in SHLIB_PATH, LIBPATH, LD_LIBRARY_PATH parameter in the BW application tra file. To fix the error, change <RV_Home>/lib to <RV_Home>/lib/64.
