This may not help much, but reading the Win32::OLE yields this nugget:
Warn     This variable determines the behavior of the Win32::OLE modulewhen an error happens. Valid values are:
0 Ignore error, return undef
1 Carp::carp if $^W is set (-w option)
2 always Carp::carp
3 Carp::croak

The error number and message (without Carp line/module info) are available through the "Win32::OLE-"LastError> class method.

Alternatively the Warn option can be set to a CODE reference.
E.g.

Win32::OLE->Option(Warn => 3);
is equivalent to
Win32::OLE->Option(Warn => \&Carp::croak);
This can even be used to emulate the VisualBasic "On Error Goto Label"
+ construct:
Win32::OLE->Option(Warn =>  sub {goto CheckError});
# ... your normal OLE code here ...
CheckError:
# ... your error handling code here ...

So, firing up an w32 box (w2k) and adding a shebang, #!C:/perl/bin -w, this is the output:

F:\_wo\pl_test>perl 696125.pl
Win32::OLE(0.1701) error 0x80041002
    after character 0 in
"winmgmts:{impersonationlevel=impersonate,(Backup,Restore)}\\localhost
+\root\wmi:BcdStore" at 696125.pl line 14
        eval {...} called at 696125.pl line 14
Can't call method "OpenStore" on an undefined value at 696125.pl line 
+16.

And, compounding my demonstration of iggerance, as applied to your comment,

It looks like the previous line openstore is not assigning the store to $bcdst

I don't see how the openstore line would assign a value to a var declared without a value at your line 15.
