--- Comment #3 from Nicholas van Oudtshoorn vanoudt@gmail.com 2010-05-20 00:23:20 --- Oops - seems there was a problem in my Wow64 build script (only the wine64 bits were being updated!)
Yes, that's the installer I was talking about. However, with a fresh wineprefix running wine-1.1.44-322-g5cc00e8, the installer still fails for me. (still with ole errors). The attached log (no WINEDEBUG options set) shows what it's complaining about.
The difference here is that the Installshield error reads "1628: Failed to complete installation"
