Mac OS X Message app cannot be opened after TRYING to install windows 10 with BootCamp

So I've tried to install windows 10 using BootCamp but somehow Windows installer didn't allow my to choose partition, I've tried to format new one inside the installer but still no lock...

so I've decided to cancel installation, everything went smoothly but Message app give me this error:

Messages cannot be opened because of a problem.

Check with the developer to make sure Messaes works with this version o OS X. You may need to reinstall the application...

How to reinstall this?

The big mistake was to let Windows itself touch the drive. It simply doesn't understand how it's faked in to thinking it's in charge. Boot to Recovery & verify/repair the disk, fix perms while you're there. Were you at least using Boot Camp 6? – Tetsujin – 2015-08-19T09:49:59.190

I'll try that. Yep, I've red that newest Boot Camp got some updates for Windows 10. Will let you know if it helps. – skacperski – 2015-08-20T10:38:38.753

Unfortunately no luck ;( – skacperski – 2015-08-24T10:09:08.770

Then I'd start with the 'first fix' toolkit. Disk Utility, fix permissions, check & if necessary repair disk. Then get the combo updater for your current OS 10.10.5 here & re-apply it.

I'll throw that into an Answer then. Glad it worked for you :) – Tetsujin – 2015-08-27T08:40:51.057
