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 which 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

Click-once cache

Windows sometimes get 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 Click-once designer if you have also an locally installed version

Earlier the designer used an embedded Internet Explorer (IE), but IE is not longer supported for login with Google, so the Google login won't work from inside the designer.

Using click-once should always get the latest version and work, but we've seen situations where the old embedded IE browser is still used, even on a Windows 11 machine.

The issue seems to be related to old designer files being used when there's an old designer version installed, even after this has been uninstalled!

To resolve this issue

1. Clear the click once 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 click-once version should work as expected
