Just a heads up!
Thought I might be able to lessen the pain for perhaps some of you installing GRLevel3_1 on Windows 10. I had no problems getting GRLevel3_2 to run on Windows 10 but GRLevel3_1 was a different story.
I installed GRLevel3_1 on Windows 10 and had a major issue in getting it to upload the files to my website. As I recall, I had a problem getting it to run on Windows 7 too. It would upload for about one hour and then just stop. I tried most everything, including running it as administrator. The fix was running it in VISTA compatibility mode and I didn't need to run it as Administrator.
The fix to Run GRLevel3_1 On Windows 10 when the GRLevel3 program icon resides on the taskbar:
Right click on your GRLevel3 icon on the taskbar.
You will see another icon for GRLevel3, right click on this icon (looks identical to first grlevel3 icon) and select properties.
Now you should be in the "GRLevel3 Properties" window, click on the Compatibility tab at the top of the window.
Under the "Compatibility mode section", put a click on the box next to "Run this program in compatibility mode for."
Under this same section, click on the drop down menu "down arrow" and select Windows Vista.
Apply/OK.
That's it, it should now upload properly.
