Qcprog.exe not found

i installed qchem but at the end, after i installed briancq, i get these messages:
(base) manos@manos:~/Desktop/qchem$ qchem test_new_install.in
You are running Q-Chem version: 6.2.1-1
QCPROG /home/manos/Desktop/qchem/exe/qcprog.exe can not be found
(base) manos@manos:~/Desktop/qchem$ qchem -nt 16 -gpu test_new_install.in

QCPROG /home/manos/Desktop/qchem/exe/qcprog.exe can not be found
(base) manos@manos:~/Desktop/qchem$

Does the executable exist at /home/manos/Desktop/qchem/exe/qcprog.exe ? The environment variable QCPROG should point to qcprog.exe, wherever it is.

No, it doesnt exist at any place.

Well, that’s a problem. Please contact Q-Chem support.
