Yeah, I'm another user with that problem. I noticed that it's only happening when I manually click to "Update Now" at the main window. Furthermore, I want to confirm the "Windows Action Center" bug. But, the new beta works much more stable than previous version. The issue that I mentioned before seems to be fixed. I haven't got any crashes of the "a2service.exe" since update. Oh, one more thing: I see that main services of EIS are 32-bit. Is there a plan to develop a 64-bit version?
