The application was unable to start correctly (0xc000007b), Click OK to close the application... I am getting this in Sonar. The last thing I had done on my computer was load up Waves API. It worked in Sonar when I opened it up and was fiddling with it a week or so ago.... I started working Reaper today just to get a quick voice over done and was loading plug ins and when I went to scan my Slate Digital Virtual Tape Plug In something came up for a Waves Plug that is loaded but not paid for yet and Reaper just shuts down....Any thoughts on trouble shooting. I might go and delete the Waves and see how it runs...

All my Sonar X1 projects are greyed out as well...

0xc000007b can sometimes indicate a disk error. Try running checkdisk on the relevant drive(s), including the C drive.

+1 on the disk being bad.

So in this situation would you guys proceed? i.e. mirror disk and reload everything?

I have 4 hard drives on this computer as well...including the bad one but one is empty...

I checked that error out and it occurs for lots of different software, and Microsoft says it means bad disk image.

I wouldn't do anything until checkdisk and/or checking the disk SMART attributes has confirmed a disk problem. Without confirmation it's a possibility, not a certainty.

Assuming that is the problem, then personally I'd make double sure I had a backup of all data, taking one urgently if I hadn't, then swap the disk out and re-install.

Bob - although MS say the error points to a bad disk image, it's also been known to crop up for other things. E.g. Adobe once put out a couple of  bad/malformed/whatever dlls that were discovered to trigger it and fixed by an Adobe update.

It's the usual problem with Windows error codes - they rarely seem to point to  just one thing. However, lots of people had problems with the Adobe dlls, and the forum doesn't seem to be over-run with X2a users having 0xc000007b errors.

Could be a third-party plugin dll though I suppose.

A hard disk check would still be my first port of call though, even if only for peace of mind.

Thx guyz, gonna go through check desk with seatools and also go back to an older version (haven't done much in several months so....) Thanks for chiming in!!!
