I'm trying to install allegro on VC++ using these instructions

This is the error I'm getting.

I searched the forums and found someone that had the exact same problem in 2005 but it didn't look like the answer was given to the problem.
My code is
#include <allegro.h> int main(void) { allegro_init(); allegro_message("Hello World!"); return 0; } END_OF_MAIN();
Thanks.
If you ask me, you would need to configure the VC project to be a 32-bit code instead of 64. However, I don't use VC++ 2005, so it is just a supposition based on a previous comment I recall.
Make sure you are using the Windows Subsystem (linker settings).
Thanks, errors are getting less it changed from what I have above to

Which was at the bottom of the first error. Any ideas, thanks.
My guess is that you did not add Allegro to the list of libraries to link against.
Thanks verrrry much.
Yea when I start every new program it looks like I have to make sure I set the linking options to what is noted below.
Under Configuration Properties / Linker / Input, add alld.lib to Additional Dependencies.
That took away the winmain error. I'm still getting the warnings concerning
conversion from int to char.

But I'm not going to worry about it because it allowed my program to compile and I was able to execute my code. Hopefully those warnings don't come back to haunt me. I hope not, anyways thanks alot, yea I can successfully compile code and run it, I thought I was stuck on Vista without allegro. I'm soo excited I can now resume my programming, yess. 
Setting "C/C++ / Detect 64-bit Portability Issues" to "No" might help.
Wow you are good, that was it.
Thanks again 
Hah, I was close
