1592090 - Getting "The procedure entry point could not be located" when opening a file from Firefox

Status: RESOLVED DUPLICATE of bug 1588975

(External Software Affecting Firefox :: Other, defect, P2)

Description

[dsilber]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.120 Safari/537.36

Steps to reproduce:

We navigate to one of our web sites that contains files we can consume with our app. We select a data file and elect to open it with our app that's installed on our machine.

Actual results:

We get an error dialog that says: The procedure entry point ??0AuthenticationAccess@MtbLicensing@@QEAA@XZ could not be located in the dynamic link library <our app.exe>

Expected results:

The app should have started and opened file.

This looks a lot like bug 1567614 ("Entry Point Not Found" message box when opening Skype for Business URL). However, that bug seems to be marked as fixed, and we're using a version of Firefox after that version (we're using v70.0 - 64-bit).

What we know so far is:

• The app runs fine normally (can directly open files of that type)
• The problem only occurs in 64-bit (the 32-bit version works fine)
• The problem only occurs with Firefox (works fine with other browsers like Chrome and Edge)

Our app consists of the main executable, and an included DLL that handles licensing. "AuthenticationAccess" is a class in the DLL, and "MtbLicensing" is the namespace it resides in.

The error dialog title says: "<our app>.exe Entry Point Not Found". It looks like our app can't seem to access the licensing DLL. Which seems...odd.

We can reproduce this bug at will.
