Strange Error: Cannot open file, eventhrough it is available.

Could you create a separate .mp file, run mptopdfon it, and send back the log?

I saw the logs linked above. Please clone the master branch and install as shown here, adapting for your setup:
https://github.com/ogheorghies/MetaUML#development

Could you try with another diagram, say:

input metauml;
beginfig(1);
    Class.A("Point")("+x: int", "+y:int")();
    drawObject(A);
endfig;
end

You may want to set MPINPUTS to include "D:\Program Files\MiKTeX 2.9\metapost\generic\metauml" or have a look at texmf.cnf. See also: tex.stackexchange.com/questions/484017/mpinputs-of-metapost, mailman.speleo.sk/pipermail/therion/2015-June/005478.html
