The application Finder.app can't be opened.

That worked Tech101Helper. Thanks so much!

In my case it turned out to be a failing firewire drive that was causing the problem. The drive finally died and I removed it from the chain, and have not had "The application Finder.app can't be opened" since.

I see that the error does not occur every time, but it must necessarily satisfy all the conditions:

1. used view mode "Column view"

2. I delete or move the folder but no file

3. folder will be deleted from the external drive or network drive

Try not to use the view "Column view" until Apple does not fix this bug in the Finder.

Ityped this in and got

(1) 2956

but the finder findow did not open. Is the problem fixed?

Thank you so much!!! This worked!!! 😀

I'm getting this error, and I haven't fideld with external hardrives or any firewire or anything like that. It just suddenly happened one day. I get the 'The application Finder can't be opened. -10810" error message, and it's increadibly frustraiting because there appears to be no solution at all. I've tried everything in this thread, and nothing has worked. I attempted to download Lion but I'm simply unable to run it. I feel like i've hit a brickwall, and I'm increadibly ****** at apple for this.

I'm on a MacBook Pro with a 2ghz intel core i7 processo, running 10.6.6. I really hope someone can help me.

Also when i tried Tech101Helper's tip I got this

[1] 64687

/System/Library/CorsServices/Finder.app/Contents/MacOS/Finder: No such file or directory

Looks like you spelled cores wrong. Try to copy paste it from here. Or use "ls" to make sure you typed everything correctly.

Based on the explanation of your laptop, you should still have support from Apple for free. I'd seriously talk to them, mention the thread and see what they have to say. 10810 messages are caused by many different problems, so it's not 10810 you're trying to fix, but the underlying problem.

10810 errors can also come about when your internal HDD is failing. In my case, Disk Utility did NOT detect the failing drive. Talk to Apple.

Downloading Lion isn't going to solve anything. It might even make things worse. I'd suggest fixing your Snow Leopard first.

I would strongly disagree with the advice not to upgrade to lion. I had this problem on my MacBook and tried all the solutions I could find on the web. I then upgraded to Lion and have never had this problem again. I suggest upgrading as the solution to this problem.

I concur that Lion may be the answer to this problem. It seems like a Snow Leopard issue; I have never experienced it under Lion.

OTOH, I dislike Lion so much that I am willing to stay with Snow Leopard, and put up with the Finder 10810 error message. I am always able to fix it by disconnecting all my FireWire devices and re-connecting them. It happens infrequently enough that it doesn't bother me too much. Lion and all of its bizarre UI changes, OTOH, would be in my face constantly, and I'm just not willing to put up with them.

YMMV, of course.

A million thanks Tech101helper:

I have been having this problem for a couple of years now.

Your solution had me scratching my head BUT IT WORKED !!!

Could you give us a little clue as to what that code means??

Many thanks

Well, what this does is, it seaarches for the directory specified. So basically it goes to the system folder, then the library folder, then the coreservices folder, and so on. When it gets to the end it sees a document/app, and opens it. You can actually do this for any app/documents.
