I received the error messagebox below upon my first attempt at running Solfege Portable.
I have not been able to duplicate this, whether I use a clean VM and fresh copy of the installer or not.

System details: Win7 x64, standard PA.c install location on P: external drive.
Note that the path shown does not exist on my system, nor has it ever.
I have also attempted installation to my local C: drive, as well as to a clean Win7 x86 VM's desktop folder.
Running a "find in files" on Solfege Portable using Notepad++ Portable, I find similar strings throughout many of the base app's files.
Was this app recompiled/rebuilt for PA.c?
