Error compiling C++ code...

[Trinthetweety]

So, I am using Windows Visual C++ 2008 edition, and I am having a rather lot of problems with it. Every time I compile my code, it comes up with this error:
"Failed to load and parse the Manifest. The system cannot find the file specified."
No matter what I put in there, it comes up with that. I compiled codes that I know to work because it has worked before, but it persists in giving me that message. I suspected that the source files were corrupt, but when I tried to delete them, it basically just flat out told me no without a reason. I am REALLY new to programming, so a simplistic answer would be great, by the way.
If there is any more information you need, I would be more than happy to give it to you, just tell me.
I thank the lovely person from the internet in advance, because I know I am really, painfully slow when it comes to programming, and I know I suck at it really badly.

This may be happening because your project was saved in a read-only space (Microsoft VS does not have the proper permission to edit the files in the project). I suggest you create a fresh project and save it somewhere that you know you have access to. That, or just run VS in administrative mode.

Also, the main function must always return int and you have to #include <stdlib.h> if you want to use system(), which I strongly suggest that you do not use (read here: http://www.cplusplus.com/forum/articles/11153/ ). You could use printf("Press the \"ENTER\" key to continue . . . "); getchar(); instead.
