First of all the graphics card does not meet the requirements. Radeons & GeForce cards are not suitable for SW & RealView.
Where did you find info stating that the GeForce GT 745M meets the "requirements". If there is a site/document that states it is capable of running realview, please direct us to it - it is wrong. As Kelvin stated, it is not supported for running Realview even though it may allow you to run SWorks.
I am sorry for the problem you are having and welcome to the forum!
This is how I fixed mine,
My Graphic card is Nvidia GeForce 210 and I don't think this is listed on SolidWorks website .
Please watch this you tube video and change the name of the graphic card on the video with yours , I used 80408 for the key.
please very careful since you are dealing with registry entries.
