Missing files on MRL Double dutch
https://www.daz3d.com/mrl-dutch-braided-ponytails-with-bonus-presets-for-genesis-9 has multiple styles available. All but 1 were working for me. It kept giving me a message that it was missing 2 files: /data/Mihrelle/MRL Dutch Braids G9/MRL Dutch Braids Scalp G9/Scalp_565560.dsf and /data/Mihrelle/MRL Dutch Braids G9/MRL Dutch Braids Scalp G9/UV Sets/Mihrelle/Base/default.dsf
I always use DIM when installing DAZ products. Since this product was giving me an error, I uninstalled and deleted it, then redownloaded and reinstalled it. Now the error message lists 10 missing files. I figured I should probably come here and ask what I'm doing wrong before I make things even worse.

I don't have it.
Compare the list of missing files, with what is installed according to DIM, and see if they are listed as installed.
And look in the log (Help > Troubleshooting > View Log File) for the full error text, or just attach that part of the log to a post.
The path of data folder in wearable presets are wrongly defined. You can fill a support ticket in here: https://bugs.daz3d.com
I ever refunded quite a few things like that... sigh ~~ The vendor directly modified DSF files but gave no test ~~
