I am using the latest version of Discovery Aim and everytime I finish a simulation, and I want to see the results, I get this error.:

Unexpected error while refreshing view WebUIView: Object reference not set to an instance of an object.

My specs are:

Lenovo y50-70

Intel Core i7 (4th Gen) 4720HQ / 2.6 GHz

16gb Ram,

NVIDIA GeForce GTX 860M

256gb SSD on Windows 10 64bit

How can I solve this?

[Sorceress Gia]

When launching the application can you try right-clicking on the program and launching it by 'Run as Administrator'?

[kristof1840]

Did not work in administrator.

Besides the error above, I get another error.
