Hi JCWolf,
I presume you downloaded the single file installer from
bts site, right? Got the same error messages of corrupted source files when I tried to install it. The reason was a corrupted download.
After a md5 check I got
ee96ed51e0082bd920e27e416c0aff30. Repeating the download didn't solve the prob -> got always the same wrong check sum [nine times].
What's your check sum?
I recommend to dl the splitted installer:
