I tried the app, and the installer dies quietly very early. It unpacks a file c:/users/$USERNAME/Temp/~ and then executes and deletes it, but that executable crashes with a null pointer write on the very first instruction after setting up the frame pointer: Wine-dbg> 0x00468208 EntryPoint in foo: addb %al,0x0(%eax) Wine-dbg>stepi Unhandled exception: page fault on write access to 0x00000000 in 32-bit code (0x00468208). Somebody needs to see what that executable does on windows.
