The Windows 10 anniversary update includes a newer version of msftedit.dll, which breaks hyperlink functionality in the text editor used by WYSIWYG Web Builder.
Until Microsoft fixes this issue we have created a workaround by installing the previously version of the DLL in the Program Files folder.
You can download the fix here:
Note that you should only install this if you have the Windows 10 anniversary update !!!
1. Close WYSIWYG Web Builder and all other running applications.
2. Run the setup
3. Follow the instructions
Hopefully Microsoft will soon fix the issues in the new version so we no longer need this workaround. A support request is pending, but usually this takes a couple of weeks...
