Application validation did not succeed. Unable to continue

Hi guys, With the latest update of cAlgo pushed by my broker I get the "Application validation did not succeed. Unable to continue" error. I have uninstalled cTrader and followed the instructions to clean the ClickOnce cache, however the app still will not install. (see below for more details) Any help appreciated.
