just finished fixing my own; i searched my own registry for IsShortcut. It appears 16 times in my own registry. i think if we can match them up, your problem might be solved. you're running utimate 32, and i'm premium 64, but i think these should match.
H_C_R / ApplicationReference = Reg_SZ with no value attached. from here on out, simply insert IsShortcut with no value, just Reg_SZ, except for the 2 with a value of "Yes"
/WSHFile = Reg_SZ value "Yes" should be entered
/WSHFILE Reg_SZ = "Yes"
Let me know if this helps, email@example.com
