I suspect that the LmUtilsU.dll is part of the FlexLM (a license manager)
If you locate that dll on you computer and right click to see its properties
there should be some company information about the dll that would confirm
this.
If the above is true then you might be using or have installed on your
computer software that uses this licensing product so I would suggest
contacting the vendor of that product. You may just have an older version of
the dll that needs to be updated.
The location of the lmutils.dll might give you some indication as to what
product is using the FlexLM license manager.
Hope this helps.
