Windows Explorer (10) crashes, ecore.exe needs 30% CPU

First: Why do you close my last Topic? There is NO SOLUTION from your side, LIMA. With the new Version it is worse than ever! I can't even work because it's crashes every minute. That must be a joke, really!

I've got a big problem with my Windows 10 Explorer (explorer.exe), which crashes very often. Now I found out, that the LimaOverlays.dll causes these crashes! My Lima-Software is up to date. Second problem: ecore.exe needs more than 30% of CPU sometimes.

What can I do?

I have the same, every 5-10 minutes. Even when the app is closed...

Same Problem here.

As soon as I install Lima the Windows Explorer crashes regularly.

I have seen this on the last Windows 10 releases happen (1703,1709).

Any solution coming up? As it is now Lima is actually useless for me.


Same problem for me on Windows 10 Pro, Version 1709, OS Build 16299.125. Computer is virtually unusable with Lima running. As soon as I quit Lima, computer works fine.


Same problem for me on Windows 7. After Lima install and reboot, Windows Explorer crashes regularly,

in particular when trying to copy-paste files and when right-clicking to paste. Quitting Lima is not enough here. Only after Lima Windows app uninstall everything is fine. Probably not a Windows 7 thing as I have another W7 computer running Lima and not showing any kind of problems. Hope this can be solved soon... otherwise the whole idea of having Lima is kind of pointless for me...

Error report is the same all the time:

Current solution after some googling and experimenting (worked for me):

1) Rename the culprit "LimaOverlays.dll" to something different... it can be found at: %appdata%\Lima\explorer\

2) Install Autoruns and look at the "Explorer" tab - disable all LimaOverlays.dll related entries (they should all be marked in yellow). Alternatively, use some other registry utility and search for all entries that have "LimaOverlays.dll" in them and disable the entries.

If you don't take step 2, opening Explorer might take some extra time... in my case up to 30 sec.


Thank you Juergen! This worked for me - sort of... I followed your procedure and now Explorer does not crash over and over again. However, I no longer have Lima in the popup menu when I right click on a folder or file. Thus I cannot set a folder or file to be offline or online-only. Not even sure how to check on how a folder or file is set.

I have sent in 4 support requests to Lima on this and other issues with no responses at all. I also see no responses from Lima in this forum so we do not know when or if to expect a fix for this. Is anyone getting a better response from Lima? (or any response at all!)


Yeah, I realize this is just a workaround. Indeed all the overlays won't show up. In my case it's not that bad as the only reason for having Lima on that computer is to access files on the Lima drive.

Some other problem popped up though using my workaround: for most picture extensions (jpg/gif/bmp) thumbnails disappeared in Windows explorer. I found out that this is related to the Lima programme adding ShellEx entries to the extension definitions in the registry (HKCR). You need to delete all the ShellEx subkeys (for extensions affected such as .jpg) as they will refer to the Lima thumbnail image handler, which is... you guessed it... the Lima dll file that was renamed. When the registry entries are deleted and the computer is restarted, image thumbnails should re-appear. I hope Lima support will finally care about the whole explorer crash issue. It's probably not their main focus as this is not happening on most computers, but the fact that there is obviously a number of affected users discussing this on their feedback site shows that their software is far from perfect. At this point I feel like I'm doing their job without getting paid for it... :S


Juergen, thanks for the quick reply. The comment you made on the thumbnails disappearing is also affecting me, so you have solved another problem for me. You truly are doing their job... I'll be editing my registry soon...

Thanks again!
