Certain pdf can't be opened in standalone version

bonedriven

Unable to run the command specified. The file or folder file:///home/Jake/.wine/dosdevices/h:/Jake/Dropbox/Portable Ubuntu/Zotero/storage/TWBZZZHU/Huang et al. - 2012 - Mg2%12xTixNi (x�=�0, 0.5) alloys prepared by mechani.pdf does not exist.

I can use "show file" and open it manually or use firefox to open it.
I remember I changed my default pdf application some time ago. But zotero doesn't seem to know that. Where do I change defualt pdf application for zotero?

(if you have your Zotero data directory in a dropbox folder - as it looks like you do - you should move it out. That'll lead to all types of problems).
