Changing Tag Data

Hello all:

I'm trying to change this -> Software   Digital Camera X-T1 Ver5.51

To this ->                                           Digital Camera X-T4 Ver1.00


At the command line, I type this: C:\Apps\Fujifilm X-T1>exiftool -software='Digital Camera X-T4 Ver1.00' dscf3438.raf
Error: File not found - Camera
Error: File not found - X-T4
Error: File not found - Ver1.00'
    1 image files updated
    3 files weren't updated due to errors

Help me please! 

Thank you for your assistance!

Assuming Windows CMD, try
exiftool -software="Digital Camera X-T4 Ver1.00" dscf3438.raf

Windows CMD uses double quotes.  Linux/Mac/PowerShell use single quotes.

Thank you StarGreek!!! You rock, and that worked!!! 

My apologies for not including my OS in the post, which is Windows 10 - will definitely do so going forward!

Merry Christmas!!
