Okay. I haven't touched my PC for 4-5 days till today. The last time I was using FASM was 4- 5 days ago and everything worked fine then but now today I tried to assemble an ASM file and I am getting output "This application can't run on your PC" and output in the console "Access Denied". The same program that was running perfectly fine 4-5 days before now can't run (I am beginner at the Assembly lang and FASM so for now I am making simple applications). As I said I haven't touched the PC for 4-5 days. I also disabled the AV software but still the same.

The OS that I am using is Windows 8.1 Core x64 bit (with disabled updates have never updated it)

You know, more information and the exact FASM program you want to run would help.

But if you didn't touch it then it has nothing to do with FASM, probably a hiccup in the OS (did you open the file in another application? restart your PC and see what happens if you try to run it again?) or you have malware or whatever.

Or antimalware/antivirus, since those are also the programs that sometimes make strange things happen.

Add "Turn off Windows defender" to above tips.

I have uninstalled the Anti-Virus software (Avast). Windows Defender and Windows SmartScreen are disabled and I am using the administrator account and still getting this: [img] https://i.gyazo.com/f75128d2f0a638e3872731078935c720.png [/img]

Looks like ASM_01.exe is 16-bit, 64-bit Windows can't run old DOS programs now.

And how did it run 4-5 days ago then? Oh people omitting important information again.

I wrote "format PE console" and "use32" at the top of my code. Doesn't "use32" mean to use the x86_32 arhitecture ?

I guess, the reason is in the 17th line of your code. Just check it carefully.

use32 makes it encode instructions in 32-bit mode. Nothing to do with format.

However, did you really write "format PE console"? Can you show the code?

The code doesn't matter. Nothing runs. I wrote a simple program, tested and still the same

Code:

format PE console
use32   ; x86_32 
entry start  
include 'win32a.inc' 

 
; This is the data section: 
; ======================================================= 
section '.data' data readable writeable  

; ======================================================= 
section '.text' code readable executable  

start: 
        mov eax, 10d

Empty sections are not supported by the Windows loader. I suspect this will be the cause of your troubles. You either need to define at least one byte in each section, or remove empty sections.

Thank you very much! The problem is solved.
