What is exactly the error you get ?
Don't know about the OP of this message, but here's mine:

The problem on my end is that my antivirus Bitdefender Total Security is flagging it as malware. In fact, it's flagging CMD as malware so simply adding an exception to this directory is not going to solve the issue.
All other commands work without issue. It's basically just unable to create the .tmp file as the process gets flagged as malware.
