Continuing to backtrack to square one and start over, in the hopes that trying again will fix the issue. Alas, it seems like I run into trouble earlier each time! Now, the installation has just gone through unpacking all the files--some I've had to extract from their download format manually--and it crashes right at the end of that process.
Right now the left hand box contains the following:
Everything is Ok
Folders: 27
Files: 257
Size: 26991752
Compressed: 26405656
C:\Black Isle\BiG World\BiG World Setup>
cd /D "C:\\Black Isle\BiG World"
C:\Black Isle\BiG World>
Error during changing into directory C:\\Black Isle\BiG World.
Exiting due to major problems.
I'm guessing the issue is that double backslash after the "C", but not sure what's causing it or where it's coming from.
Idk, did you maybe accidentally type that as the directory where BG1 was when you told BWS where it actually was?
