I just install the LabView 7.0 runtime engine for Linux, but the install appears much larger than the 4,702,252 bytes you mentioned. The /usr/local/lib/LabVIEW-7.0/liblvrt.so.7.0 is 7,328,272 bytes, and the /usr/local/lib/LabVIEW-7.0/lvapp.rsc is 2,773,251 bytes. Can these files be removed and still have the run-time engine work?
