This missing version (x86) 8.0.50727.762 from the error you posted leads to this file. Its 2.6mb. https://www.microsoft.com/en-us/download/details.aspx?id=5638 // After installing it load asset manager again from launcher and the bin folder. If it doesn't work then use sxstrace again and there will be a newer error.
Finally now the asset manager starts from both the launcher and the / bin folder .... thanks to all of you who helped me to solve the problem! +1 respect for all
