Updated to Kontakt 5.5.1...Now it's dll file is gone...SOLVED by CCLarry The Great!

Have not seen that issue here. My Kontakt 5.dll file is located in:
 
c:\Program Files\Cakewalk\Vstplugins
 
If you do a search in Windows explorer for Kontakt 5.dll does it turn up anything?

@rtucker.
 
Nope...upon search, no such animal exists now.  Or absynth.  Weird...
 
(and that's the same folder I kept my NI stuff in)
 

Wow, that is a little spooky. I tried to send you the Kontakt 5.dll but it is ~42MB and my email won't allow me to send anything over 25MB.

Turns out it ate all my 64 bit Kontakt5 dlls, my Absynth5 dlls, and my Replika dll.
This is odd because I DID update both Kontakt5 AND Replika...but NOT Absynth5.
 

That doesn't sound right...

May want to run a V-Scan also....sounds fishy...

Have you tried re-installing and seeing if it fixes itself?

Sounds like you may have had a network interruption during the update. If that's the case, then it's an indication of poor design on NI's part. Installer Design 101: you rename the old file rather than deleting it, and you don't delete the old file until the new one is in place and its checksum has been validated. 
 
My dll, btw, is in Program Files\Cakewalk\Vstplugins\Kontakt. I don't remember if Service Center put it there or if it was my own customization.

Again...after doing a search on my box there is NO Kontakt5 dll of any sort. There is no Absynth5 dll of any sort. And there is no Replika dll of any sort...although I only have the free version of that. NI has sent me a link to a VST tool program...who knows what it will do...that I will try tomorrow. I'm still positive that all I really need is the latest Kontakt and Absynth dlls to be back in business. But I'll probably end up having to reinstall them both and simply forget about Replika. I'm also pretty sure Larry has the right answer on this one. Never let the service center install your updates...install them yourself so you will know where they are going.

And thanks...I'll keep ya posted as to how it goes tomorrow:-)

Got the email ol pal! Will load them up tomorrow at the studio and let you know what happens. Stay tuned friends!!

I recently did a big update with Komplete Ultimate 10. Then there were some Service Centre updates too. Several of my plugins were uninstalled. As it turned out the add VST version was not checked when I ran the installers individually in verbose mode. So I had to run the installers again this time making sure to check that VSTs were selected on each installer.

Sheesh, nobody should have to jump through those hoops to install any software. Knock on wood - metaphorically, as there's very little wood in here - but I've never had any major issues with Service Center. Yet.
 
I learned long ago that with these control-freak vendors that you should always accept defaults for everything. Even that's not a guaranteed defense when they subsequently change their mind about where stuff should go. Why can't everybody be like FabFilter and Meldaproduction? A DLL and a license file, drop 'em anywhere that makes sense and you're done.

 I seem to be unique in having that problem with NI.

I have to chime in my agreement with that. I reckon just about everything can and will be cracked- the difference is the integrity of the user who is and who isnt willing to be honest and fairly compensate others for their work. Further, our costs are increased to help pay for more elaborate and cumbersome protection schemes
