About Liberty Street Software

Liberty Street Software was founded by Paul “The Professor” Dembowski in 1997. Based out of Mississauga, Ontario in Canada we specialize in Hobby Inventory Programs. Catalog, track, value and appraise your coin, stamp & paper money collections. We also develop a home inventory program called HomeManage.

CoinManage, the first piece of software made available to our customers came to Paul while vacationing in Chautauqua Lake in New York. After seeing several advertisements in COINage magazine, he realized he could design and supply a more professional and easier to use product. Since the age of eleven, he has been an avid stamp and coin collector, keeping track of his collections in spiral bound notebooks. It is no surprise that he has devoted his life to creating software that organize, calculate and track virtually anything. Over the years, Paul has worked for several of the world’s leading Windows software companies in both the United States and Canada. He has gained an incredible amount of insight and knowledge that is applied to all the software he creates.

  1. I running ver. 2015 of Stamp Manage and every time I backup bt collection the software abends and restarts.I’m given the option to email the crash report,, but every time I try it tells me it is missing the email address. It doesn’t tell me if it is my address or the address I’m submitting to. I get no prompt for an address and I don’t see anywhere in the software where I can enter one. Any help would be useful. Thank you, Patrick

You may not have the appropriate permissions to access the item” I also tried as administrator with the dame results.
