A couple of remarks on installation and setup Windows7 pc, based upon my attempts at installation :-)
1. Placing the zip file in the MoI directory did not permit unzipping there. (Administrator privilege not yet invoked.)
2. Copying the unzipped files from elsewhere may work?, but see item 4.
3. Running 7zip on the zip file from a download directory, and selecting the MoI directory in C:\programfiles(x86)\MoI3.0betaNov-19-2013 did
permit extraction of the files, but, see item 4.
4. It was necessary to right click on MoI.exe and select "run as administrator," in order for the customUI folder to be found.
---Success---. It is not necessary to select "run as administrator" again.
