Hi everyone, I'm a beginner Python programmer and I'm currently facing an issue with a program I've been working on. While the program runs perfectly fine in Visual Studio Code, it encounters an error when executed as an executable file. Specifically, a particular function is not working as expected. After investigating, I found that the program is unable to locate three specific DLL files that are dependencies of pdfium.dll: ext-ms-win-oobe-query-l1-1-0.dll ext-ms-win32-subsystem-query-l1-1-0.dll ext-ms-win-gdi-edgegdi-l1-1-0.dll I suspect that these missing DLLs are causing the issue. I've already tried the following solutions: System File Checker: Ran sfc /scannow as administrator. Windows Updates: Installed the latest Windows updates. DISM: Attempted to repair the system image using DISM, but it got stuck at 62.3%. Visual C++ Redistributable: Installed the latest 32-bit and 64-bit versions. Unfortunately, none of these solutions have resolved the problem. I've also tried specifying the paths to the DLL files using tools like PyInstaller, but it hasn't made any difference. I'm using Windows 11, Python 3.12, and a 64-bit version of pdfium downloaded from Git. I would appreciate any help or suggestions on how to resolve this issue.

Python Program Error: Missing Specific DLL Files

Hi everyone,

I'm a beginner Python programmer and I'm currently facing an issue with a program I've been working on. While the program runs perfectly fine in Visual Studio Code, it encounters an error when executed as an executable file. Specifically, a particular function is not working as expected.

After investigating, I found that the program is unable to locate three specific DLL files that are dependencies of pdfium.dll:

ext-ms-win-oobe-query-l1-1-0.dll
ext-ms-win32-subsystem-query-l1-1-0.dll
ext-ms-win-gdi-edgegdi-l1-1-0.dll

I suspect that these missing DLLs are causing the issue.

I've already tried the following solutions:

System File Checker: Ran sfc /scannow as administrator.
Windows Updates: Installed the latest Windows updates.
DISM: Attempted to repair the system image using DISM, but it got stuck at 62.3%.
Visual C++ Redistributable: Installed the latest 32-bit and 64-bit versions.

Unfortunately, none of these solutions have resolved the problem. I've also tried specifying the paths to the DLL files using tools like PyInstaller, but it hasn't made any difference.

I'm using Windows 11, Python 3.12, and a 64-bit version of pdfium downloaded from Git.

I would appreciate any help or suggestions on how to resolve this issue.

Hello, the tag “Visual Studio” is related to Visual Studio, for more questions about Visual Studio Code, you can post it to the GitHub-vscode forum where you would get support for this product. Thanks for your understanding.

Specifically, a particular function is not working as expected.

This observation does not provide any information to help diagnose a problem. Be specific when providing error information and related error codes and messages.

What you think are missing DLLs are actually what Windows refers to as Api sets. Refer to the documentation at API sets for a more detailed discussion.

It is likely that the absence of a physical file for the identified API sets is confusing the issue.
