FCIV fails to find some files when hashing C drive

问题

I'm building a batch program integrating fciv, certutil and powershell for compatibility on hashing folders on legacy systems. I ran into a bug where fciv will not hash some files while doing recurse hashings, below is a snippet of the code used.

"%workingDir%fciv.exe" "\\?\%targetDir%" -%hashType% -r

For example, i am scanning C:\Windows\System32\wbem\en-GB , results from FCIV shows that it scanned 67 files, while CertUtil and Powershell methods scanned 166 files. I tried to scan individual files that did not show up in FCIV's scan, below is the command

C:\Users\User1\Desktop\FileFinder\fciv.exe" "C:\Windows\System32\wbem\en-GB\aeinv.mfl" -md5

i was thrown the error below

Command Line: fciv.exe -r C:\windows\system32\wbem\en-GB\aeinv.mfl 

c:\windows\system32\wbem\en-gb\aeinv.mfl\*
    Error msg  : The system cannot find the path specified.
    Error code : 3

It seems to think that the file is a folder and throws an error. I can provide more details if needed, thanks in advance!

Edit: Seems that at least 1 other programs out there have the same issue

http://compressme.net/ (CHK Hash Tool)

Edit2: Appearently there isnt a issue if you use a 64bit variant of CHK Hash Tool, i'm guessing it's something related to that but i have no lead
