Can't start VC application in Portal 7.3 tc~wd4vc~launcher error

Hello,

we are trying out visual composer 7.30 with Portal. After developing in VC and deploying to portal I can't start the application. In the log-files there is the following message:

Application sap.com/tr-gruppe_impl cannot be started. Reason: it has hard reference to application sap.com/tc_wd4vclauncher, which is not active on the server because  application is not deployed. Probably refering application sap.com/tr-gruppe_impl declares runtime but no deploy-time dependency to the referred application which is wrong. Deploy the component sap.com/tc_wd4vclauncher or contact owners of application sap.com/tr-gruppe_impl to check their references..

I have read several threads that tc_wd4vclauncher doesn't exist in portal 7.30, but these threads don't offer or describe a solution which fits my problem.

Do I have to deploy the missing component? If, yes where can I get it?

Please, does anybody have met the same problem and solved it?

Thanks in advance,

Kind regards,

Lu
