Hello Anonymous Monk, Can you provide us a sample of a key to decode? What does it mean dose not seem to work? Is there an error? The output is not as expected? What do you expect what you get? Update: Is your question related with (Finding Windows XP CD Key)? It seems like it. Update2: Similar Retrieving Microsoft licence keys from your computer. Seeking for Perl wisdom...on the process of learning...not there...yet!	[reply] [d/l] [select]

I'm pretty sure that's because the original code may have been written against a 32-bit version of windows, but you are on a 64-bit version. Can you confirm this?	[reply]
