Weird, it should be in %temp% since it's extracted after giving admin privileges to Toggle Tweaker. Maybe you are running Toggle Tweaker under different conditions.
1. From where are you running Toggle Tweaker? (browser downloads window? explorer window?)
2. Which folder is Toggle Tweaker located?
3. Do you have UAC enabled? (do some programs ask for admin privileges?)
4. Is Toggle Tweaker asking for Admin privileges on startup?
Even if UAC is disabled when you allow it by clicking YES it should Run okay
