Go to https://ultimaker.com/software/ultimaker-cura. Click on find previous versions. Click on 4.5.0 and scroll all the way to the bottom and you will find the EXE file

The main download page only let me download the MSI installer. I had to search in previous versions, 4.5, and found the EXE installer. Tested and works great now. Thank you

I am having the same issue. when I double click on any STL file whether its in a zip or not, it will not automatically open with 4.5 like it did with any previous version. I even try to right click, open with but does not have cura 4.5 listed as an option.
