Can't tell why it's not installing from that log. Maybe a log like this WINEDEBUG=+msi wine SageInstantAccounts2011.exe > log.txt 2>&1 would tell us more... but don't paste that log, save it to pastebin.com or something and just give us a link. Which version of wine? You might also be able to bypass the installer and just copy the installed app from windows to .wine/drive_c, but that won't copy any registry settings.
