Westinghouse PC1100 PLC Programming software?

[Ntec Solutions]

Hi,
 
I am currently working on a project to replace an existing Westinghouse
PC1100 plc.
 
I was wondering if you have the PLC programming software to enable me to
open the customers Program CD copy. This would allow me to easily
convert the program.
 
Would you be so kind as to point me in the right direction. As I am just
about to give up?
 
Best Regards
