I opened the file in a newer version of MATLAB, I think it was 2017a and the upgrade procedures which shows when you open a project from an older Matlab version in new one, fixed my project file.

Some people have been able to recover appdesigner use if they rename their prefdir -- that is, a preference might have messed something up.

Same problem here with 2017b. The file runs ok with double click, but won't open in AppDesigner. I can also unzip it and read all content, so I guess it is not corrupted.

I am having the same problem. mlapp file was created in 2016b and modified in 2017a. Tested on 2 computers with 2017a...runs and opens fine. Tested on 2 computers with 2017b...runs fine but won't open. Dialog box saying 'Error loading XXXX.mlapp' but no other information.
