Error: "Cannot load library app_links_plugin.dll" on Enigma Virtual Box (Flutter Project)

Hi everyone,

We're facing an issue with a Flutter project that we package using Enigma Virtual Box (v11.20).

Setup:
We're developing the app with Flutter.

After building the app, we use Enigma Virtual Box to package it into a single .exe.

The packaging is done on Windows 10 Server, and the resulting .exe is distributed to both Windows 10 and Windows 11 machines.

The app is also digitally signed.

Problem:
Sometimes, after packaging, we get the following error:

"Cannot load library app_links_plugin.dll"

We've noticed two possible causes:

This error can randomly appear after packaging, even if the file paths seem normal.

If the folder name (where the .exe is located) includes Turkish special characters like ç, ğ, ş, ö, the error always occurs.

We’re trying to understand:

Is this a Unicode/encoding issue related to Enigma Virtual Box?

Is it related to how Flutter loads dynamic libraries?

Or is there a known issue when plugin DLLs are loaded from non-ASCII paths?

Any advice, workaround, or solution would be much appreciated!

Thanks in advance.

Hi, please confirm if problem happens on ARM version of Windows only?

The issue does not occur only on ARM-based machines — we also experience it on Intel-based systems.

Enigma Virtual Box is running on Windows 10 Server 2020 Standard, and we are performing the packaging process on a PC with an AMD Ryzen processor. The operating system is in English.

Our end users are using both Windows 10 and Windows 11.

Do you think the problem could be related to the fact that I’m running Enigma Virtual Box on Windows 10?

We’ve also noticed that most of the users who encounter the "Cannot load app_links_plugin.dll" error are on Windows 11.

Yes, we got your email, thank you for that, we will reply as soon as find the core of problem!

Thank you sir.

Just to follow up, issue is fixed, it is related to Virtual Box, fixed since EVB version 11.30, Enigma Protector 7.90.

Thank you for your close attention, the issue has been resolved—great work, well done. Enigma Protector Family
