Hey Paul,
 
After a short look at your GEDLog the error reason is quite clear. You start GED.exe from the folder F:\A7_x64, but GED can not find the folder F:\A7_x64\GED (or any file in it - like the widgets or the core-INI file).
 
So please go through the following checklist to solve the problem
1) Check if the folder F:\A7_x64\GED exists
 - if not, please reinstall GED into this folder
2) If it exists, please check if the GED folder has a size of 373.374 bytes
3) If the size is correct please check if you have read/write access to the complete folder
4) If you have read/write access please check if the problems are solved when starting GED with administrator rights (rightclick -> start as admin)
5) if non of the above points help, please give us all information about your computer system you have (especially: do you have a 32 or 64 bit operating system?).
