The .NET cal Setup.exe crashes (0xE0434352) on 218-378-13 series ISOs
even when filenames are clean (no trailing-space bug). Previously only
bypassed when the ' _' trailing-space signature was detected. Now
detects by probe series ID in the data filenames too and always does
direct file copy for 218-378-13.
