XFileSharing Pro - I get an error when starting the installation of the script

[igaiga3]

Hello.
I added all the modules as in the instructions, but I get an error when starting the installation of the script.

error log:
[Mon Mar 02 17:37:07.071347 2020] [cgi:error] [pid 4845] [client 195.110.33.162:59062] AH01215: Can't locate Session.pm in @INC (@INC contains: Plugins Modules . /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5) at install.cgi line 5.

The problem with line 5 in the install.cgi file
#!/usr/bin/perl
use strict;
use lib '.';
use XFileConfig;
use Session; - this line and what is the matter?
