--- Comment #2 from Rosanne DiMesio dimesio@earthlink.net 2011-09-25 06:42:45 CDT --- I already deleted the wineprefix that log was created from, so I can't check that one.
I just re-ran the installer on a clean wineprefix, and this time the line complaining about sqdedev.DLL refers to "C:\users\dimesio\Temp\msi60a5.tmp". That file exists in the Temp directory, but there is no msi60a5 folder.
I also retested with winetricks dotnet20 installed, and that log also shows an error about sqdedev.DLL not being found, but the installer completes and reports success.
