Windows 8.1 OSD could not parse

This link describes my problem http://xpro.se/blog/2013/11/12/mdt2013-error-when-deploying-windows-8-1/#respond but I wanted to run it by you first.

I my case my only problem is with windows 8.1 64bit.

Not sure whats changed all of a sudden but it doesn't work but 32 bit works fine.

Also, if I apply the fix does that mean my MAK won't install anymore?

Thanks
