INstalling next cloud application on WIndows error: could not create folder "/username/files"

I have a user who tried installing nextcloud on here computer. It is th enext cloud app for synchronizing.

Th esoftware runs, but in th eend, when th efoldr is to be created on their ocmputer, it gets the error:
Could not create folder “/username/files”

Why might this be happening?
