$ perl -MWin32::OLE -wle 'print Win32::OLE->new("ADODB.Connection")'
Win32::OLE(0.1709) error 0x8007007e: "The specified module could not be
found" at -e line 1
        eval {...} called at -e line 1
Use of uninitialized value in print at -e line 1.

With a debugging OLE lib and perl:

$ perl5.13.8d-nt -Mblib -we'use Win32::OLE;
Win32::OLE->new(q(ADODB.Connection))'
Win32::OLE(0.1709) error 0x8007007e: "The specified module could not be

        eval {...} called at -e line 1

$ gdb perl5.13.8d-nt

This needs now printf debugging, oh my.

I crosschecked with strawberry on the same machine, where
ADODB.Connection is registered.
c:\strawberry> perl -MData::Dumper -MWin32::OLE -le "print
Dumper(Win32::OLE->new(q(ADODB.Connection)))"
$VAR1 = bless( {
                 'Properties' => bless( {
                                          'Count' => 14,
                                          'Item' => undef
                                        }, 'Win32::OLE' ),
                 'ConnectionString' => 'Provider=MSDASQL.1',
                 'CommandTimeout' => 30,
                 'ConnectionTimeout' => 15,
                 'Version' => '6.1',
                 'Errors' => bless( {
                                      'Count' => 0,
                                      'Item' => undef
                                    }, 'Win32::OLE' ),
                 'DefaultDatabase' => undef,
                 'IsolationLevel' => 4096,
                 'Attributes' => 0,
