Sharing programs over home network

[A6TH]

Hello everyone. I'm having a problem understanding how to share a program from a Windows 7 PC over a home network, so other network users can open it on their Windows 7 PCs. The reason I'm asking this is: I shared a program about a year ago and it worked perfectly, I just shared a directory where it was installed and it opened like charm on all other network PCs. The problem is, it won't open anymore. When I try to open it, it can't find a directory. I'm not sure what permissions I should set. I think when the program is run on a network PC it requires some resources from a local PC, which it can't get. How do I know which resources it requires, so I can set their permission too. I can't set the permission to the whole C: drive, but, if I could find which resources the program uses, maybe I could somehow solve this problem. What do you think?

I finally managed to share the program. The only problem were Windows Credentials. After I set them up, everything works like a charm.
