KathyM has asked for the wisdom of the Perl Monks concerning the following question:

Hi, there. I have written a programme in Perl that is to extract the default file paths from Microsoft Word and Microsoft Excel, then write them to a file. However, the programme only works on the PC I created it on and I'm struggling to understand why. I realise there must be something different about the PC I created it on, but I don't know what. The PCs, while different models, are all running the same OS (Windows XP SP2), same version of Office (2003) and same version of Perl (ActiveState Perl 5.8.6) with all the same libraries installed.

On a PC other than the one I created it on, the programme starts, then exits with the message:

"Use of uninitialised value in print at open_excel_7.pl line 54, <STDIN> line 1.

"Can't call method "Options" on unblessed reference at open_excel_7.pl line 60, <STDIN> line 1."

Here is my code. The subroutine for Excel works on any machine, it's only the Word subroutine that doesn't, so I have omitted the code for the Excel routine in order to save space.

Any suggestions anyone has will be most appreciated.

Thanks,

Kathy.
