Firstly, I checked the installation files and found that all the DLL files are present. Then I checked the computer NET FRAMEWORK 3.5， For Win11 computers, it also exists. And I use administrator privileges to install and run the software. I have tried on two other computers, Windows 10 and Windows 11, but they did not run successfully. Unfortunately, the link mentioned in the latest reply cannot be opened properly, so I don't know how to solve it. I look forward to your reply and help. Thank you very much.
