When you are working with the Turnkey, it is advisable to run the latest version of MDriven Designer.

The latest MDriven Designer is always available via this link: MDriven Designer

The link is a ClickOnce application installer that will refresh MDriven Designer to the latest version before starting.

ClickOnce works natively in Edge but requires a plugin for Chrome and Firefox:

• Recommended Chrome plugin:  Chrome
• Recommended Firefox plugin: Firefox

Fix Problems

ClickOnce cache

Windows sometimes gets confused by which ClickOnce application has been cached and gives an error.

To clear the cache, start a command prompt with administrator privileges and execute.

Portal Google Login Problems Using ClickOnce Designer if you also have a locally installed version

In earlier versions, the Designer used an embedded Internet Explorer (IE), but IE is no longer supported for login with Google - the Google login won't work from inside the Designer. This embedded browser has not been replaced with "WebView2".

Using ClickOnce, you should always access the latest version and work, but there have been situations where the old embedded IE browser was still used, even on a Windows 11 machine.

The issue seems to be related to the usage of old Designer files when there's an old Designer version installed, even after this has been uninstalled!

To resolve this issue:

1. Clear the ClickOnce cache as described above
2. Uninstall any locally installed old version of the Designer in Windows "Applications" settings
3. Install a new version of the downloadable Designer
4. You can now uninstall the new Designer again, and the ClickOnce version should work as expected

If you still have problems, try going to Windows Installed Apps and repairing "Microsoft Edge WebView2 Runtime".
