Open program on startup Win 10

[bobbyspangles]

I have a program I would like to open on startup but nothing I've tried so far seems to work.

• There is an option in the programs settings to enable open on startup but that does nothing.
  
• I have tried to add a shortcut to the program in both shell:startup and shell:common startup - no luck.
  
• I have added the location of the .exe to HKEY_LOCAL_MACHINE/SOFTWARE/WOW6432Node/Microsoft/Windows/CurrentVersion/Run .
  
• And I have tried disabling UAC

I think it may have something to do with permissions as it starts up OK in Admin, but I would like it to work on my User account. I also get prompted every time I start the program in User for the Admin password.

Any ideas please?
