We have recently converted our WiX Toolset installer from v3 to v6.
The upgrade seems to have gone smoothly.
However we are now seeing the following errors in the msi log file
msiexec /i setup.msi /l*v setup.log
Log file entries with errors all prefixed with "DEBUG: Error 2826:"
Control BottomLine on dialog PrepareDlg extends beyond the boundaries of the dialog to the right by 4 pixels
Control BottomLine on dialog WelcomeEulaDlg extends beyond the boundaries of the dialog to the right by 4 pixels
Control BottomLine on dialog ProgressDlg extends beyond the boundaries of the dialog to the right by 4 pixels
Control BottomLine on dialog ExitDialog extends beyond the boundaries of the dialog to the right by 4 pixels
I have searched the codebase at https://github.com/wixtoolset/wix and can't find any clues as to why this is happening.
I'd guess it's a cosmetic issue no one has noticed as DEBUG messages in the log file are generally ignored with other noise. The WiX Toolset is an Open Source project. This could be a great way to make your first contribution.
