Critical system failure during Guardant driver installation

Last updated: December 27, 2022
Attention to users of Windows 11

Problem/Issue

Most of the time, Windows 11 comes with memory integrity control turned on by default, and Windows 10 users can do the same. The Guardant driver will not install properly if this parameter is used during installation.

Solution

We strongly recommend that you disable memory integrity control before installing the Guardant driver. Read more: Core isolation

To disable this option:

  1. Press the Start button and enter 'Basic isolation'.

  2. Select Core Isolation system settings in the search results to open the Windows security application.

Compatibility between AMD Radeon graphics card and LIRA-CAD

Last updated: December 15, 2022
The situation was detected on the following models of AMD Radeon graphics cards: RX 5500M, RX 6700 XT, RX 460, RX 470, RX 480, RX 580, RX Vega 7 (integrated graphics card for AMD Ryzen 5 processors 46xx, AMD Ryzen 5 56xx, AMD Ryzen 5 75xx, AMD Ryzen 7 47xx, AMD Ryzen 7 48xx).

Description

Since December 2022, our support team has been receiving the following issues: after updating Windows on computers with AMD Radeon graphics cards, the LIRA-CAD software crashes. Versions with a start screen (beginning with LIRA-SAPR 2020) are opened and display the start page. However, it is not possible to create or open any models as the program closes with no warning. Without the start screen, older versions, including non-commercial 2016, simply crashed on startup.

Problem/Issue

Compatibility problems between LIRA-CAD and the upgraded Adrenalin Edition 22.11 driver are found for several Radeon graphics cards. This driver has a bug in the OpenGL library that LIRA-CAD uses. This driver is automatically installed on computers where Windows Update is enabled and the driver update option (enabled by default) is installed.

Solution

Use graphics card driver version 22.5.1 of 05.2022 or earlier versions to make the LIRA-CAD module function properly on computers with a Radeon graphics card. The driver is available on the AMD website.

Solution No.2 Added March 15, 2024

For versions 2022 and 2024, we propose the following solution:

  1. Download the archive and unpack its to any folder.
  2. Run the AliasingDetector.exe file and remember the value (see the red frame on the image below) that is displayed in the window.
