Update application

1.I have 14 workstations and 1 central computer (on WS´s is installed the main application which i want to update, and for that purpose i will create the clone of the program dir on central computer with the same structure of subdirs and this folder will be shared)- For this example let say that the central computer has IP [login to view URL] and one of the WS´s IP is [login to view URL] and we have shared folder on central computer and this folder has the subdirs of the main program. Let say that this folder is MainProg. When i want to access this folder on CC (Central Computer) i type in Win explorer: \\[login to view URL]\c\MainProg and to connect to this folder i have to input login data for CC. [login to view URL] remote locations are connected to VPN including HQ (central computer) and speed varies of each remote location, but speed is not smaller than 4Mbits/ 512 kbits. 3. The total size of installed main application is aprox.40MB, so the size of each update varies; sometimes there is total size of update of 15 Kb and sometimes the total size of files for update is 5MB Please check detailed description of this app in attachment. Application must be multi language prepared. The primary language will be english and i need preparation for one more language. Who will develop this app will have a possibility for further payed development. The price i am willing to pay depends on how good the application will be but not under 50$
