Can't launch SU anymore

Hello,

today SU 2015 won’t launch. I saw this previous post but that’s not my problem.

Bugsplat.log contains:
BsSndRpt.exe: 2015-03-10 09:24:52 AppKey: it
BsSndRpt.exe: 2015-03-10 09:24:52 MFA: MSVCP100!00026be8

I can’t upload the dmp file here (please allow this file extension too).

I suspect it’s a problem with Microsoft Redistributable package, updated today via Windows Update. On a side note, they create more problems than they solve. I’ve tried to reinstall the MSVCP but to no avail.

What should I do to reenable my SU?
Thanks.
