Hi Game_Code_here,
Thanks for your fast reply.
I solve this problem by following steps:
1. Install Battle.net and Starcraft.
2. In NVidia control panel. Set StarCraft running in GPU mode.
3. Launch it and play once. (Just make sure my hardware & software environment are OK to run games)
4. Turn off Microsoft Defender. (I already have PC-Cillin)
5. In NVidia control panel. Set AppGameKit Studio running in Integrate graphic mode.
Now both Set AppGameKit Studio and ParticleEditor can launch without error.
Thanks to everyone who view this thread.
Nice day,
Stanley Hsu
