LPub3D shows splash screen but won't run


LPub3D shows splash screen but won't run
#1
Hello.

I just installed LDraw_All-In-One-Installer_2024-01_setup_64Bit_v1.exe over the weekend to make a MOC of a bus based on the 80s/90s style of LEGO sets, since the only 3 I found were 696-1 (Bus Station), 379-1 (Bus Station) and MOC 90011-1 (Bus), which were not to my liking.

I used LDCad 1.6d2 to make my custom model and it worked fine. I also used LDView 4.5 to get a parts list and it also worked fine.

The problems started when I tried to run LPub3D 2.4.7.75 to create instructions for the set. On one computer, on 1st run I pointed to the LDraw library folder, but then I only get a splash screen and the program doesn't run.
On the 2nd computer, on first run I instead opted with the "Extract Archive" button but it results in the same symptom, when I run the program it only shows the splash screen for a second and doesn't start. This is what the log shows:

I'm using Windows 10 Pro x64 on both computers and I have all Visual C++libraries from 2005 to 2015-2019 installed. One computer has a Core i7 M640 and the other has a Xeon E5450, both on the older spectrum of CPUs. Are there any special requirements for the program to run?

Perhaps it would also be sensible to create a ticket on Github, because Trevor can tell you 99% of the time where the problem is based on the log files.

If nothing goes right, go left.

Thanks, I tried the latest version (EXE on one PC and ZIP on the other), the first still only shows the splash screen, and the 2nd stopped showing the splash screen all together.

I'll definitely try the ticket path to find out what the problem might be.
