Description Giovanni 2016-03-07 07:29:22 CST 
After updating Fiji, the program does not start anymore (stops before showing the GUI).
In debug mode it stops before loading the plugins, i.e. the last line is 
[DEBUG] Discovered user interface: org.scijava.ui.swing.mdi.SwingMdiUI
In order to reproduce the error, I downloaded the last 64-bit release and, without adding plugins and update sites, I tried to launch the update and select only subsets of components. It comes out that the program can not restart after the update of
jars/imagej-legacy.jar
Updating only its dependencies does not give any problem.

Can you check your temporary directory[1] and see if there is a file called "ImageJ-xxxx-_0-7.stub", where "xxxx" is your user name?

If so, try deleting that file and restarting Fiji.

This file is created by the "Single Instance Listener" function of ImageJ, to ensure only one instance is running at a time. I think there is a bug where it isn't deleted after updating, so when you restart afterwards it tries to connect to a "running instance" that doesn't actually exist.

If you're not able to find this file or directory please let me know.

Comment 2 Giovanni 2016-03-07 09:26:14 CST 
It worked! In the Temp directory I found a version of the file dated 18/02/2016. After removing it, I could run Fiji. I also tried to reinstall it from scratch, and to launch the update, and it worked fine after that.

Thanks.

Thanks for testing and reporting back, Giovanni.

I'll try to figure out a more robust way to implement the single instance feature, since it's both confusing and frustrating that the temp file didn't get deleted.

I'll leave this issue open until it is universally fixed.

Thanks again!

I believe this is fixed in the 0.19.2 release[1]

Note also that the temp directory is often hidden, as can be the .stub file itself. To see hidden files on Windows please see:
