This has been going on for some time. In essence this is the problem - a typo in the URL:
https://free.nchc.org.tw/osdn//crystaldiskinfo/77081/CrystalDiskInfo8_16_1.exe
Note the double slash in the URL: ... osdn//crystal ...
Typing this into Google Chrome actually works, because the // is overlooked. However, PatchMyPC continually fails due to this error.
Replacing the // with / also works in Google Chrome, and I suspect would work in PatchMyPC
