As the title, after updating, I click on the RUN shortcut or WebGrab+Plus.exe, a window just blinks once and then disappears.
I tried to remove version 3.3 and reinstall version 5.1, the problem persists.
Please help me, what do I need to know?
Thank you!

install dotnet 7

all you need is the runtime,scroll down and its the last one on the right.
.NET Runtime 7.0.12
Hello,
I have the same problem as the first post when update version 5.1 to 5.3.
I also install .NET Runtime 7.0.20 but it didn't resole the problem.
Can you help?
I asked ChatGPT and install .NET Runtime 8.0 and the program is working now.
