Upgrade to Contextcapture Update 15 seems didn't update correctly. Engine runs but running Master shows error that application is missing dependencies. Not sure why it looks for files on c:\temp
Seems environment variable CC_INSTALL_DIR_FOR_BUILD is causing this but without it doesn't run at all. Reinstallation didn't help.
Had to create new variable CC_DESKTOP = C:\Program Files\Bentley\ContextCapture\
and it fixed the problem.
