Every time I try to change directory, to A:\Diablo III it gives me an error "The folder you selected cannot be used, please contact support"
Aside from this I tried changing directory to my B: which is a normal non-raid drive, same error.
Any ideas on how to fix this? My C: is super low on space.
Alternatively, if I have to install to C, would it be possible to move the data files to another drive afterward or would too many registry entries be looking at C?
