Unsupported 16-Bit Application

[Hossen]

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int a, b, c, GCD;
    a = 10;
    b = 20;
    for (c = 1; c <= a && c <= b; c++)
    {
        if (a % c == 0 && b % c == 0)
        {
            GCD = c;
        }
    }
    printf("%d\n", GCD);
    return 0;
}

After run this code a pop up window show this message

The program or feature "\??C:\Users\Hossen\Desktop\C_Time\Alg\bin\Debug\Alg.exe" cannot start or run due to incompatibity with 64-bit versions of Windows. Please contact the software vendor to ask if a 64-bit Windows compatible version is available. )

Here is my build log

Build message mingw32-gcc.exe -Wall -g -c C:\Users\Hossen\Desktop\C_Time\Alg\main.c -o obj\Debug\main.o mingw32-g++.exe -o bin\Debug\Alg.exe obj\Debug\main.o Output file is bin\Debug\Alg.exe with size 28.48 KB Process terminated with status 0 (0 minute(s), 0 second(s)) 0 error(s), 0 warning(s) (0 minute(s), 0 second(s))

Help me to solve this problem?

This "??\" in front of the path is strange...
Things you can try:
1) Can you run your program directly? Note, this will probably only flash shortly with a black screen, because you have no input at the end of your program, so it will close imediatly... (see http://wiki.codeblocks.org/index.php/FAQ-Compiling_(general)#Q:_My_program_runs_in_codeblocks_but_if_i_start_it_from_the_outside_it_only_flashes_and_closes_immediately )
2) Do you have any anti virus running?
3) Have you installed any old compiler on your system?
4) Try a fresh rebuild (Build->Clean, Build->Build)


generally, if you post code or logs please use the code tags in the forum editor (the # symbol)

I don't have any anti virus except windows diffender.
How do i check my compiler is old or new?

[BlueHazzard]

Open a command line:
1)  Start (or windows flag now)->type in

Code Select Expand

cmd
hit enter
A black window apears
in the black window type

Code Select Expand

where mingw32-make.exe

Post the output here. You can Copy text from the window by klicking on the top left corner of the black window->Edit->Mark Select the text and hit enter. Then you can paste it here

what about 1) and 4) ?

[Hossen]

after refresh  and rebuild everything is same as before.
I don't know how to run program directly.

gcc-9.2.0
NFO: Could not find files for the given pattern(s).

1. open file explorer.
2. navigate to the folder with the exe
3. press f4 (this selects the path control)
4. type cmd
5. type the name of the exe in the new command prompt window and press enter.

Windows defender is an antivirus software. And it is pretty aggressive and annoying. Most probably it is causing you these problems.
