use OLE is a compatibility layer for applications using the old toplevel OLE.pm. # New code should use Win32::OLE. Try

#!perl
use strict;
use Win32::OLE::Const "Microsoft Excel";

printf "Perl %s\n",$^V;
printf "Win32::OLE Version %s\n",$Win32::OLE::VERSION;

my $excel = Win32::OLE->new('Excel.Application') 
   or die Win32::OLE->LastError();
printf "Excel %s\n",$excel->{'version'};
print "excel <$excel>\n";

$excel->{Visible} = 1;

my $workbook = $excel->Workbooks->Add 
   or die Win32::OLE->LastError();
print "workbook <$workbook>\n";
my $sheet = $workbook->Worksheets("Sheet1");
$sheet->Activate;
print "sheet <$sheet>\n";
