For reasons unknown, when I try to open the LDView.exe it only shows on the task manager for 2 seconds and then disappears. It was working before (about a week ago), I had everything setup to run LDCad, convert with LDView, and render in POV-Ray.

LDCad and POV-Ray work just fine, but LDView suddenly stopped operating. I have tried everything I know, including but not limited to cleanups, scans, check disk, defrag, etc. And went on and did a clean installation of the LDraw AIOI.

After re-installing the AIOI, LDView is still not working. Any ideas on troubleshooting? Everything is updated to the latest (stable) version in the PC (I avoid betas).


----------
Update:
  • The effect appears to only be caused by AMD drivers, I will keep track of this for the next updates.
  • You can immediately gain back the use of LDView by uninstalling the Radeon Software (in this specific case, meaning if you updated to anything after 20.12.1).
  • If you would like to have access to the video card functionality with the previous version of the software, you can download it on the official AMD website by clicking this link and scrolling down to the installation package: Radeon Software version 20.12.1
  • In the very rare event that the uninstall fails, AMD provides a cleanup tool that you can run to remove traces of the Radeon Software. Follow this link for the AMD Cleanup Utility.


----------
Tested updates that break LDView 4.3 functionality:
  • Radeon Software version: 21.2.1 (Optional update released: 2/1/2021)
  • Radeon Software version: 21.3.1 (Recommended update released: 3/10/2021)
  • Radeon Software version: 21.4.1 (considered a Recommended update released: 4/13/2021) 1

- Optional update: This means that the update does not contain critical fixes from AMD, rather some minor specific changes. If these changes do not affect the use of your video card you can skip the optional update (if you haven't installed it yet) until the next recommended update is available.

- Recommended update: This is a standard stable driver update that AMD recommends to all users of their cards. Recommended updates often include new features and fixes.

1 Also tested with LDView 4.4 Beta 4 test release.

I have no idea, but you might try uninstalling the LDView you got from the AIOI and installing the latest official 64-bit LDView release standalone.

I did what you suggested, but the behavior remains the same. Later found out that both versions work fine in Safe Mode so, I'm in the process of selectively killing processes and services to see what is messing with the program start. So far it appears to be a memory access issue of some sort. But as you probably know, in Windows everything is a "maybe".

I'll update at a later time with my findings.

Is this a virtual machine or HW?

This is a standard Windows 10 Pro machine, my daily use home PC.
I was unable to find the cause of the problem. In the interest of not wasting time I decided to install a backup that I had made recently. It is all back to normal now.

However, I will keep an eye to see if it happens again and if I can catch whatever created the problem. I found at least one other (not related) program misbehaving, which tells me that something was going on within Windows.
Same Problem here.
@Leonardo Gonzales what kind of Graphic Card are you using? I have a AMD RX5700XT, also on Win10 Pro with all Updates

My current setup is:
OS: Windows 10 Pro version 20H2 (OS Build 19042.746)
CPU: Intel Core i7-3770 3.40GHz
GPU: Asus Strix Radeon RX 590
Radeon Software version: 20.12.1
RAM: 16 GB

I've been holding on updating the Radeon Software and slowly applying the changes I made before to the computer in order to find if something I did affected the LDView.

What Radeon Software version do you have?

latest: 21.2.1

I tested LDView using the Radeon Software version: 20.12.1 and it works as expected. Then without making any other changes, updated the Radeon Software and upon restarting after completing the installation LDView no longer works.

I can confirm, without a doubt, that the Radeon Software version: 21.2.1 breaks LDView 4.3 (in both 32-bit and 64-bit).
