Boxedapp packer packed executable finds for file outside package

Question

i have two files from which one is the main executable and other is run by first one. I want to pack these files into one executable, but with boxedapp packer or enigma virtual box the main executable file searches for the other file outside the packed exe file. I tried the option share virtual environment with child processes but it did not work. By the way the main exe is made from vb.net which needs a file in current directory. Please help me.
