Hi ching ping,
Every time we create a new build and new release we create new versions of all 4 WebUI related installers:
- Dev Edition installer
- QA Edition installer
- Run Time Edition installer
- WebAii Framework installer
It is important that all your machines are kept in sync and use the same version. So if you upgrade your developers to Q3, you also need to upgrade the Run Time Edition running on your build server to a Q3 version. You should be able to download the new Run Time Edition installer from your account (or whosoever account owns the license).
Failing to keep all the machines in sync will create incompatibilities somewhere in your build and/or testing process.
