RevokeMsgPatcher is a patch for WeChat/QQ/TIM that enables multi-instance and prevents message recall. It supports these three social apps on Windows. I primarily use it for the multi-instance feature!

Usage
This software is portable and requires no installation. The latest v2.0 supports WeChat 4.0. Open the software, choose your app and apply the corresponding patch for the desired feature.
Anti-Recall
After applying the anti-recall patch, even if someone recalls a message, you can still see it on your WeChat! As shown below, however, both anti-recall features have some minor issues.


WeChat Multi-Open
After installing the multi-open patch, double-clicking the WeChat desktop icon once opens a login window. Double-click as many times as you need to open multiple WeChat instances. This is very handy for those managing multiple WeChat accounts.

Environment
- Windows 7 or later.
- .NET Framework 4.5.2 or later.
How to Use
- Close WeChat/QQ/TIM before using this program.
- Run this program as an administrator, and wait for the latest patch info to appear in the bottom right corner.
- Select the install path of WeChat/QQ/TIM. For the installed versions, the program automatically retrieves the path from the registry; for portable versions, you need to manually choose the path.
- Click ‘Anti-Recall’. The interface may become unresponsive for a while; just be patient.
Uninstall
It’s a portable program; simply delete the relevant files.
