Can't find executable file that is obviously present

I am trying to run the COMSOL license manager in Pop OS; however, when I try to run: $ ./lmgrd -c ../license.dat -l /var/tmp/comsol55.log I get the following error: > bash: ./lmgrd: No such file or directory The lmgrd file is clearly present in the current directory. Running ldd lmgrd gives the following output: linux-vdso.so.1 (0x00007acd5ec0d000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007acd5ebf0000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007acd5eb09000) libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007acd5eae9000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007acd5e800000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007acd5eae4000) /lib64/ld-lsb-x86-64.so.3 => /lib64/ld-linux-x86-64.so.2 (0x00007acd5ec0f000) Is the issue here that the first dependency is missing? If so, what package is required to add that in Pop OS?
