tms install with iw 12.1

I am trying to install 4.8.0.1 - iw12tmsgriddedxe2_xe2.bpl in XE2 with iw12.1.23

 
When I compile this I get the following error
 
[DCC Error] E1026 File not found: 'iw12tmsgriddedxe2_XE2.otares'
 
How do I proceed?

Can you please make sure you are using the correct package?
The bpl file should be called iw12tmsgriddedxe2.bpl and there are no references required to ".otares" files
