Just purchased Komplete 10 for my new PC that I built and after the initial installation I was able to open all the instruments in either standalone mode or within Cubase except Kontakt and Battery. I let the installation prompts install the programs in the default locations and service center recognizes all plugins as activated. K5 and Battery are in the same directories as the working instruments. NI installer tool confirms this as well. But when I select either of those two to open I only get a brief hourglass followed by nothing. There are no error messages and no indications that there was anything screwy with the install. I have now uninstalled and reinstalled Komplete 7 times with the same result. Beyond fed-up. My system is offline so I performed the offline activation. Massive, Absynth, fm8, Reaktor, Guitar Rig all work beautifully. I have also tried installing Kontakt and Battery separately from disc A with no luck. Firewall is turned off as is anti virus. If anybody has any ideas I would be grateful. Running windows 7 64 bit Home premium.
