I find that after downloading both the source and no-source .rar files (ver. 4.20), I get an error message ("The archive is either in unknown format or damaged" when using WinRAR, and "Cannot open file" when using 7-zip). I cannot unpack them or even view them. Any ideas?
I don't have a problem using 7-zip. Unblock the .rar file first. Then use the 'open archive' file menu option rather than trying to double-click the .rar file.
How do I unblock the rar file? I don't see any option for unblock when I right-click the rar, and I can't load into winzip. I get: Cannot open file: it does appear to be a valid archive.
