Hi Otrhan,
Thank you for you suggestion, I tried that, but still the same.
I think my issue may not be the same one as EOS-ERR-1603
Under path: C:\Program Files\Epic Games\RealityCapture
I found the exe file with name: AppProxy.exe, and double click on it. I see the error message as my question described.
I even run the RealityCapture-1.4.0.msi file, but I can’t install successfully.
Best,
Golden Q
