This might be a 32 bit / 64 bit problem. I have 64 bit Windows 10 but have 32 bit Office 10. This code works when I tried it on Portable Strawberry 32 bit but not with 64 bit perl. 

#!perl
use strict;
use DBI;
my $dbfile = "c:/temp/Database.accdb";
my $dsn = 'driver=Microsoft Access Driver (*.mdb, *.accdb);dbq='.$dbfi
+le;
my $dbh = DBI->connect("dbi:ODBC:$dsn", '', '') 
   or die $DBI::errstr;;

print join "\n",$dbh->tables();
