Okay I think I may have ANOTHER solution. Apparently it works for quite a lot of people (this is really for the people on Windows 7 since that despises Crawle for whatever reason). The instructions are below:
Type in 'cmd' into the search bar on the start menu and right click it and run as admin.
Then type in:
Now make sure dx8vb.dll is in System32
Drop me a comment saying if it works or not, I'd appreciate it.
