This is my first post. Hope I'm putting it in the right place. Yesterday I had an interesting experience that someone may be interested in. I have been using QU and VMFusion v3 on an iMac for some time now with no problems. Yesterday, I upgraded to VMFusion v4. Later that day, when I went to print some photos, I kept getting error message jpeg error #54.  After doing all the suggestions I found here and other places, upgrading QU, and wasting several hours, it dawned on me that maybe VMFusion v4 was the culprit. Short answer, it was. I uninstalled it and reinstalled v3 and all works well with QU now.  Has anyone had a different experience?  Thanks.

Will do, Mike
