I have 5 years experience with AppMon and have used EasyTravel to demo for the past years.
However, after upgrade AppMon to version 7 and reinstall EasyTravel to latest version (18.104.22.16800), now I cannot start EasyTravel anymore.
The OS is Win10 64bit on my laptop with AppMon 7.0.5
Below is the error in command prompt.

The version that goes with v7.0 is 18.104.22.16858. I would try downloading it and running both the fat client and web client to see if that helps any. Don't download the latest version, but the version specific to v7.0:
To add to what Dave said. Check out the details on the easyTravel download page. The team recently added the disclaimer about which version supports which appmon release: https://community.dynatrace.com/community/pages/viewpage.action?title=Demo+Applications+-+easyTravel&spaceKey=DL#DemoApplications-easyTravel-Download(Installer+License)
