Access denied when accessing tasklist::get_proc_params(i.get_pid())

[webnoob]

I understand this is a permission issue but I've just re-installed windows (going from 10, to 11) and am now getting access denied WIN32_ERROR(5) when trying to use tasklist::get_proc_params(i.get_pid()).

I'm just trying to get the file name the process was booted with but this is stumping me.

I'm the only user on my PC so have admin etc.

I just the comment against the package

remember some infomation need higher privilege in some specific windows versions

I guess this is the issue. Running my app as admin doesn't seem to help though.
