Hello. I am trying to change the Application tag in a tif using the command "exiftool -Application=4.00 167.tif" but the following results is "Warning: Sorry, Application is not writable Nothing to do". Is it really not writable or am I doing something wrong?

What is the full name and group of the tag? Run this command (a variation of the command in FAQ #3) and post the exact output.
exiftool -G1 -a -s -Application file.tif

Looking through the Tags Names documentation, while there are a lot of tags that have "application" as part of the name, there are only a couple tags called only Application

There is XML:Application in MS Office files such as DocX. Obviously not applicable here.

The only other one is an MRC (Medical Research Council) tag. And that is a different file format than a TIFF. If you look on that page, you'll see that none of the MRC tags are writable by exiftool.
"It didn't work" isn't helpful. What was the exact command used and the output.
Read FAQ #3 and use that cmd
Please use the Code button for exiftool output

Please include your OS/Exiftool version/filetype

My apologies, Stargeek. I had wrongly assumed there was an "Application" tag as labelled by Adobe Bridge (see screenshot). I should have checked this by looking at the results of an exiftool query. Had I done so, I would have seen that the tag is called "Software" which I was able to successfully change the value of. I was also thrown by exiftool saying that the "Application" tag was not writable. Sorry for the confusion!

No worries. Programs like Bridge try to take some of the madness out of metadata by giving you simple names. But a name in Bridge might read multiple tags to fill that value.  For example, "Description" in Bridge might be reading the XMP:Description, IPTC:Caption-Abstract, or EXIF:ImageDescription tag.

My guess would be EXIF:Software for "Application".

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

Thank you for understanding and yes, Phil, I see it is Software now. You help and suggestions appreciated
