Problem with running Matlab Block function

Below is the error I receive after I start the simulation. Running as an administrator didn't work for me. Please advise!

Making simulation target "PROJECT_FROMSCRATCH_sfun", ...

The error says "cannot open input file 'C:\Program Files\MATLAB\R2011a\lib\win64\libippmwipt.lib' " - is this file present in your installation?

[Subesh Aryal]

Solved! I simply had to copy and paste libippmwipt.lib to the current directory.

Subesh: Glad that worked, but you really shouldn't have to do that. Perhaps you'll want to explore this further later at your leisure. :)
