Hi there,
If you have iTunes from Apple $atan, and it is version 12.5 try this. I did and wonders of wonders it worked...
?BlackBerry Link has stopped working? after updating to iTunes 12.5
Good luck.

That did the trick for me

I had tried uninstalling & reinstalling blackberry 10 desktop software (link + drivers only) multiple times without any luck. It always crashed. After reading this thread, I tried 2 new things which currently has blackberry link running again:
1. uninstalled iTunes
2. Did a silent install of bb link.

Here are the steps I followed:

I used ccleaner to uninstall:
- iTunes
- Blackberry 10 Desktop Software

I went to these folders and deleted any folders with 'Blackberry', 'Research In Motion', 'Apple', 'Apple Computer' or 'iTunes'
Warning! This will delete settings and programs. You will lose your iTunes library & more, so be careful!
C:\ProgramData\
C:\Users\<userid>\AppData\Local\
C:\Users\<userid>\AppData\LocalLow\
C:\Users\<userid>\AppData\Roaming\
C:\Users\<userid>\Music

In ccleaner, under 'Registry' I scanned an fixed any issues.
In ccleaner, under 'Cleaner', I did "Run Cleaner".

I made sure my blackberry was disconnected from PC

I restarted the PC.

In ccleaner, under 'Registry' I scanned an fixed any issues (again).
In ccleaner, under 'Cleaner', I did "Run Cleaner" (again).

I did a quiet/silent install of just blackberry link and drivers using BlackBerryDesktopSoftware_1.2.0.52_B59.exe as per: How to install BlackBerry Link without installing BlackBerry Blend using silent install

Waited about 5 minutes and noticed blackberry link shortcut on desktop.

Started up blackberry link and it doesn't crash.

Connected blackberry 10 phone and it is recognized by Blackberry Link. I lost all settings though. Still works after restarting computer.

This worked for me, thanks for posting.

I updated to 10.3.3 and now Link doesn't complete the backup. It detects and connects, but that's it.

Would completely re-installation of Link work?

I found that the iTunesPrefs.xml file in the current user profile folder was the real culprit. Simply find and rename or delete this file. No need to uninstall and reinstall Windows, BlackBerry Link or iTunes.
