1.0.5-r2 Arduino.h IPAddress.h Client.h and more: 'file does not exist'.

I am new to Arduino trying to set up the 1.0.5-r2 IDE to compile known-working sketches that were created using this version of IDE on another computer that no longer exists.

I have newly installed IDE 1.0.5-r2 on Windows 7.

The sketches I've been given contain files that have includes i.e:

#include "IPAddress.h", #include "Arduino.h" and #include "Client.h" as well as other *.h files that are located in:

Program Files (x86)\Arduino\hardware\arduino\cores\arduino

When I attempt to verify each sketch I get a list of errors saying that these *.h files do not exist.

I am hoping this is a common 'rookie' issue.

Can anyone offer me any guidance?

Please post the sketches, you will probably need to add them as an attachment. If you click the “Preview” or “Reply” buttons you will see a link appear “Attachments and other options”.

I can successfully compile the following sketch with Arduino IDE 1.0.5-r2:

#include "Ethernet.h"
#include "SPI.h"
#include "IPAddress.h"
#include "Arduino.h"
#include "Client.h" 
void setup(){}
void loop(){}

Does it work for you? If not please post the FULL error output using code tags(</> button on the toolbar).
