Triton 3.10 windows error: The system cannot find the file specified

I am getting error when run the test (see below). Traceback (most recent call last):

Can you print out the content of cc_cmd before running ret = subprocess.check_call(cc_cmd)?

[roman8ivanov]

[woct0rdho]

Do you actually have this cl.exe in its folder? What happens if you open a new PowerShell and type cl?

[roman8ivanov]

[woct0rdho]

What is the path of that cl.exe? You can type Get-Command cl to show its path

(Things can get weird if one installs multiple versions of MSVC)

[roman8ivanov]

[woct0rdho]

So it seems you have installed multiple versions of MSVC. The one in your PATH is not the one found by Triton and shown in cc_cmd

(My code first try to find MSVC using vswhere, then using PATH. You can see the details in windows_utils.py in this repo)

Maybe you can uninstall all other versions of MSVC and only have one left, then try again

[roman8ivanov]

It is strange as I don't have this folder: 'c:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.38.33130\bin\Hostx64\x64\cl.exe'

[woct0rdho]

Before I thought that vswhere should be more reliable than PATH but now I'm not so sure... Maybe you can edit triton/windows_utils.py, remove the find_msvc_base_vswhere() part in the function find_msvc(), then try again

[roman8ivanov]

I keep getting the same error after removing find_msvc_base_vswhere() part in the function find_msvc().

[roman8ivanov]

I fixed issue. I had by chance another system variable with wrong cl.exe path.
