MM2.0 quit and won't start anymore

Usage & Issues
#1

Hi community.
I’ve succesfully used MM1.4 and MM2.0gamma (last version 20200324) since many years and never had an issue like this before:

Last Monday I had a session for several hours and had left everything on for a coffee break. I came back and wanted to continue with next sample, and nothing worked. MM2 was totally frozen and I had to quit it from Task Manager (64bit Win10). In itself nothing spectacular BUT that it does not start anymore is. When launching I get the ImageJ main bar and nothing else.

Typical procedure follows: make a back-up copy of the installation on external drive, remove and reinstall the software. No change, still only the IJ bar appears, although that seems to be functional. It says JAVA 1.8.0_152 which is different from the Java on my PC (271).

Really standing on the hose now, anyone ideas?

Cheers,

m

Same problem here for 2 days now.
I uninstall everything (MM2.0, Fiji and Java) and reinstall everything no success.
After that I create a new user account (administrator, using windows 10) on the pc and there MM2.0 launches. You can then put back your profiles and load the configuration again but I still lost part of the configuration.
Would be happy to hear if someone has another solution to make it run without creating a new user account (which brings other kind of problems later on such as need to reinstall pClamp completely etc…)

Cheers

Ah,

sounds like it could be a win-bug. Checkcheck…

Julien.
your hint was correct: under a new standard user all works, I can also load the existing hw profiles without a problem.

An explanation and a fix, anyone?

Hi Mika,
Glad it worked :slight_smile: but I’d also like to have a way to fix it on the old user account to avoid to have to set up everything again

Do I understand correctly that the Micro-Manager splash window (where you select the user profile and hardware configuration file) never show up? If so, then ImageJ fails to launch the Micro-Manager plugin. You can try launching it manually, by selection it from the ImageJ plugins menu. That likely will also fail. You could see if the code produces a Corelog file (a file with the appropriate date in the Corelogs directory with the Micro-Manager directory). If so, it should contain a stack trace indicating what exactly is going wrong.

However, the only thing that persists on a single Windows user account is the Micro-Manager profile directory. It is located in the User’s “home” Directory, in “AppData” (note this is a hidden directory, and you will need to make it visible first), “Local/Micro-Manager/UserProfiles”. You can (temporarily) move that directory elsewhere to see if that makes a difference.

Dear Nico,

Thanks for the tip, this worked and made my day!

I transferred the complete folder with MM UserProfiles to a third disc and MM could start normally. It also re-populated the UserProfiles folder again. I don’t have any other than Default user profile but perhaps Julian could test if after successful launch with empty folder one can bring the old user profiles back.

Cheers,

Mika

Nice! If you still have the “faulty” user profile, it would be great if you could email me a copy. Issues like this crop up regularly and are very difficult to trouble shoot. I would love to reproduce the issue so that I can change the code to at least have Micro-Manager start up.

Sure,

I just need your email…seems to gotten lost during the years.

Hi guys,

I also tried Nico’s solution and it did work as well for me. I can access again MM on the old user account and I loaded all my configuration successfully.
Thanks So much for your help Nico, you saved me a lot of troubles!

Cheers
