Why is RUNAS not running?

Question

cmd/bat

Good day! There is a need to run one software on the side of the user on behalf of the administrator. On the seven rescued a batch file of this content

runas /savecred /noprofile /env /user:PC\Administrator C:\TLC5000\TLC5000.exe

In the top ten, when starting the batch file, it gives an error 267 The folder name is incorrectly specified.
However, if you just open CMD and paste the design, everything works out fine. How to be?
