Paperport 10.0 deleted by repairman.Lost discs and...

Question

I have used PaperPort 10.0 happily for a while.I had my PC repaired and they deleted the program from my PC ( & two others I used a lot. )I cannot for the life of me find the installation discs. How can I reinstall this great program???They say the info is still retrievable from the PC but not without the program reinstalled.Thanks for your help.Jeri Brofman
