Does your machine not have a drive labeled C: ??

An identical bug came up during development in which a machine that did not
have a C: drive would throw exactly this error. However, it was marked fixed.

I can confirm that in my case there is no C: drive.

I have the following setup:
A: = FDD
D: = DVD ROM
E: = CD Writer
F: = SATA HDD
