MMEX 1.3.3 not opening: MMEX Instance Check

[fjcmurphy]

Hi!

I've installed the latest stable version
mmex_1.3.3_macos10.9-wx3.0.2build.dmg
on my Mac running macOS 10.12.6 (Sierra).

Whenever I'm starting MMEX I get the following error message:
"
MMEX Instance Check
MMEX is already running...
Multiple instances are no longer supported.
"

I've checked the Activity Monitor and have also restarted and reinstalled MMEX several times; but I don't see that any MMEX instance is actually running on my machine. MMEX is simply not starting up.

I have no idea what caused the issue and I'm not able to find an older version of MMEX which is not crashing.

Does anyone know what I could do please?

Thank you for your help. I really need to access my financial records which I've built up over years now.


Regards,
Frank

What was the previous version that you were using?

What was the previous version that you were using?

I don't fully remember; but I have the tendency to use MMEX regularly and do always update apps to the latest stable versions if updates are available. I would guess really the previous stable version for macOS.

After I've received the error message:
- I've fully uninstalled the app (using AppCleaner) and reinstalled it: no change in Error message
- I've tried to downgrade to v1.3.0, v1.3.1, or v1.2.7: either no change in Error message or there was a message that I could not open the file due to corruption

Could you please try to run it off the disk image (don’t drag it to the applications folder)?

[fjcmurphy]

Yes! That works and I can also load my MMEX DB. Yeah

Would you know how to fix the issue then and how to install it properly?

Thank you.

Honestly, that was a bit of a shot in the dark. Glad it worked though. I haven’t heard any other reports of that error and I am not getting it on my system, so it is hard to tell what the problem is on your system. Do you typically open from the Applications folder, launchpad or dock?

I have all my apps in the Application folder and open them typically via Spotlight Search. But I also get the error message when I open it directly from the Application folder or via a terminal.

What a strange problem.

How I've installed the MMEX in the past:
- I've double clicked mmex_1.3.3_macos10.9-wx3.0.2build.dmg and then
- moved (in the opened window) the MMEX icon to the right to the Applications folder icon (link alias)
This lead to the error.

Your trick, just opening the MMEX app directly from the mapped drive kinda "motivated" me to install the app not via the above mentioned opened shell, but move the MMEX icon directly to the Applications folder.

This seemed to have worked! Now I can normally start the MMEX app. No clue what the issue is/was.

Thank you for your help and support!!

Catch same problem today. Just out of the blue. 1.2.7 works fine. Anything above that just crash with a Instance check curse.

Running from disk image doesn't help. Installing, re-installing, deleting too. Need help. I can't use 1.2.7 because of custom fields in newer versions.

Thanks!

Just to add my "me too". Something changed in the past few weeks. I am on MacOS 10.13.5 (17F77)

When I try to launch mmex the icon does appear, and it is possible to command-tab over to it, but nothing is there. The name appears in the menu bar but there are no options, and it is not possible to quit. It does appear in activity manager. The only way to get rid of mmex as an active process is to kill it in activity manager.

some sort of security feature in MacOS??

I am been using the windows version in W10 through VMWare on the mac. That works well.

thanks for a great product!

Same issue with me tring to drag and open from Application 1.3.3 (Mar 04, 2017) versionnot opning same tried from dmg also not working using mac os 10.13.5

[LexGary1]

I got it to work by deleting the app in applications and all of the support files in ~/Library/Application\ Support/mmex then reinstalling.

[LexGary1]

an update on this - I did get it to work one time by doing the steps I outlined. I tried to launch a second time and it is back to the same problem. It crashes and upon reopen becomes a token process which cannot be exited and has no windows (but also is doing nothing).

I redid the steps that worked twice, with the same failure.

I am left with VMWare + W10 on the Mac, and the windows version of mmex in the VM - that works.

Same problem suddenly today. I am on Mac os mojave 10.14
When I open it, MMEX Instant Check says that it is already opened, and it is not.
It worked well until yesterday, not anymore today.
I have deleted the app, reinstalled it, still does not work.
Who can help?

All of these are not marking the things easily which are so uncomfortable seriously

Hi,
"me too". Same problem as LanBoNa. I tried more and more reinstallation, but no solution.

[justslymo]

Anybody find a solution for this annoying problem???????????

I'm not super tech and have been struggling to get my MMEX database open - I too keep getting the Instance Error message

Poking and prodding I found an MMEX document that simply contained numbers - 413 I think. Anyway I deleted it and lo and behold no more 'multiple copies no longer supported' error message!

For how long time will tell

Incidentally I have the 1.3.3 version and am running OS 10.15.2
