"Hey there, it seems like every time I restart my PC I get the following error when starting dropbox.
Couldn’t start Dropbox. This is usually because of a permissions error. Storing your home folder on a network share can also cause an error.
For the first few times, I had the error, I followed the "Permission errors" and "access denied" error resolution and it worked, however, that no longer resolves the issue. I completely uninstalled and reinstalled dropbox and it started working again, but now it's doing the same thing after a restart. I can't keep reinstalling dropbox every time I want to use it. Does anyone know what's going on and how I can fix it?"
