Hi!

We have experienced three different issues with Lync 2013/Skype FB lately.
There were two KBs that crashed Lync/SKB on startup, KB3054946(The Norwegian LanguagePack part of it) and KB3055014.
We solved those issues by removing the updates, but we remain with two computers that still experience the issue.

To get the two remaining computers to work with Lync/SFB we have to manually delete the SIP-folder/Cache inside it.
For every network change from wired to wireless we have to remove it. Every time it crash on one of those computers it states that the faulting module name is uc.dll.

We have tried to reinstall lync, recreate the uc.dll file and massive amounts of google searches.
I have added the report.wer file from one of the crashing computers below. Any ideas?
