Tutorial fails with Missing DLLs

[mherrmann]

Do you have a file api-ms-win-crt-*.dll anywhere on your system?

[mherrmann]

(And in particular api-ms-win-crt-multibyte-l1-1-0.dll.)

[titusz]

yes multiple versions of it ... but not in system32 ... I even put a copy there and it still fails with the same error... very strange

[mherrmann]

It still fails with FileNotFoundError: ...api-ms-win-crt-multibyte-l1-1-0.dll even after you put the file there?

[mherrmann]

And where - in which paths - are your versions / copies of the file please?

[titusz]

Yes...

[titusz]

This is where I have copies:

[mherrmann]

Very strange... And when you do

python

and then

from shutil import copy
copy(r'c:\Windows\System32\api-ms-win-crt-multibyte-l1-1-0.dll', r'C:\Users\titusz\Code\fbstest')

?

[mherrmann]

And maybe when you run the command prompts as Administrator?

[titusz]

This is weird... yes it also fails ... even with admin console:

even copy pasted the dll filename from explorer to make sure there are no typos.
I also tried other files from System32 folder ... also not able to copy ...
Maybe because python is installed to nonstandard C:\Python35\ path ... I do a reinstall

[titusz]

Did a reinstall of Python 3.5.4 32-bit... now it fails with: FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\titusz\\Code\\Envs\\fbstest\\Scripts\\python3.dll'
There is only a python35.dll in that folder for my fresh installation.

[mherrmann]

Do you have a full stack trace?

[mherrmann]

Are you using the default Python from python.org or something else like Anaconda?

[titusz]

Default python from your tutorial link ... the 32-bit installer

[mherrmann]

Does it work when you delete the lines

python_dlls = (
    'python%s.dll' % sys.version_info.major,
    'python%s%s.dll' % (sys.version_info.major, sys.version_info.minor)
)
for dll_name in python_dlls:
    remove(path('${freeze_dir}/' + dll_name))
    copy(join(dirname(sys.executable), dll_name), path('${freeze_dir}'))

in C:\Users\titusz\Code\Envs\fbstest\lib\site-packages\fbs\freeze\windows.py?

[titusz]

Yes i am back to the FileNotFoundError: [Errno 2] No such file or directory: 'c:\\Windows\\System32\\api-ms-win-crt-multibyte-l1-1-0.dll. I can copy some of the files from System32 via python... but not all. Must be some permission thing.

[titusz]

I got the freeze working, by removing the code as you suggested and adding C:\Program Files (x86)\Windows Kits\10\Redist\ucrt\DLLs\x86 to the path . This helped. Should we close this issue or is this something that should be mentioned in the tutorial. I like the idea of "cross-platform desktop apps in minutes, not months" very much :)

[mherrmann]

Glad you like it :-) I'll update fbs so it handles this case better, or tells the user install the Windows 10 SDK.

One thing that I'd still need your help with please: You got a FileNotFoundError: python3.dll. But you do get a python3.dll in target\Tutorial after python -m fbs freeze right? Where else on your system do you have python3.dll?

[titusz]

Yes with the deleted lines as suggested I get a python3.dll. My venv/Scripts folder does only have python35.dll and no python3.dll. The venv was created via PyCharm (if that matters). The python3.dll that ends up in the freeze is from the python base installation: c:\Users\username\AppData\Local\Programs\Python\Python35-32\python3.dll

[mherrmann]

Okay. I just released a new version of fbs and the tutorial that should help with the issue you encountered:

1. It searches more locations for python3.dll to (hopefully) avoid the FileNotFoundError.
2. If api-ms-win-crt-*.dll can't be found, it gives a helpful error message along the lines of the link you posted.

Could I ask you to test this @titusz?

1. Download the latest version of the tutorial.
2. Use PyCharm as before to create the virtual environment and install the requirements.
3. Run python -m fbs freeze.

Hopefully it should be more helpful now. Please do let me know!

Thanks,
M

[titusz]

Just ran a test and I can confirm that the new version works fine. 👍

[mherrmann]

Great, thanks!

I am getting this error even after installing the SDK. Have run fbs freeze in both powershell and administrator command prompt and still getting this error. Full stack trace:

FileNotFoundError: Could not find api-ms-win-crt-multibyte-l1-1-0.dll on your PATH. If you are on Windows 10, you may have to install the Windows 10 SDK from https://developer.microsoft.com/en-us/windows/downloads/windows-10-sdk. Otherwise, try installing KB2999226 from https://support.microsoft.com/en-us/kb/2999226. In both cases, add the directory containing api-ms-win-crt-multibyte-l1-1-0.dll to your PATH environment variable afterwards. If there are 32 and 64 bit versions of the DLL, use the 64 bit one (because that's the bitness of your current Python interpreter).

SOLVED: Added to User PATH environment variable (NOTE: System Environment PATH already contained necessary key value when this error occurred)

[mherrmann]

Which Python version are you using? And which Python versions does fbs support?

[atlas4292]

Which Python version are you using? And which Python versions does fbs support?

Hi Michael! Yes this issue was later identified after solving this one and the executable would not run. fbs freeze runs (the command itself) successfully regardless of the Python version. While the generated output in the target folder does not work due to the versioning as you said, this is not the underlying cause of this issue. I have updated with a "solved" at the bottom for anyone who might come across this post. My Windows permissions are layered across many aspects and so it is easy to forget the necessity behind the separation of the users environment variables and the systems. For most general Windows users, this will never happen.
