Missing resource DLL such as A64RESENGL.DLL: reinstall over the existing installation

Audience

This article is for EasySIGN and MasonART users, IT administrators, and support teams who need to repair an installation after a missing resource DLL message appears.

Primary use cases

Use this article when:

• EasySIGN shows a message that it cannot find or load a resource DLL.
• MasonART shows a message that it cannot find or load a resource DLL.
• The message includes a file name such as A64RESENGL.DLL.
• A program function, such as Archive, no longer opens correctly.
• The installation appears damaged, but the user wants to keep existing archive files and settings.

Customer scenario

A user tries to open a function in EasySIGN or MasonART and receives a message that a resource DLL cannot be found or loaded.

The user may be concerned that reinstalling the software will remove archive files, customer data, worksheets, or settings.

In this situation, reinstalling over the existing installation is the recommended repair method.

Summary

When EasySIGN or MasonART reports that a resource DLL is missing, install the software again over the existing installation.

Do not uninstall first.

Installing again over the existing installation repairs missing program files while preserving archive files and settings.
