Programs can't acces network shares

Just upgraded 2 computers, a laptop and a desktop to windows 8, clean install.

I shared my files on the desktop and mapped it to my laptop as a network drive. i am able to access it through explorer and programs like chrome but some programs can't even see the drive. Tried using UNC paths but the programs still can't seem to access the shares. Both computers are on the same homegroup. Granted Everyone full control to the folder, advanced shares, blah..

Am I missing something?
