Summary: Photoshop 7.0 tryout installer seems to hang on 99% of
                    preparing setup
           Product: Wine
           Version: 0.9.42.
          Platform: PC
               URL: http://www.fileplanet.com/59113/50000/fileinfo/Adobe-
                    Photoshop-7.0-Trial---Win32
        OS/Version: Linux
            Status: NEW
          Keywords: Installer
          Severity: normal
          Priority: P2
         Component: wine-misc

In reality it's only a 60s delay. It's because the downloaded executable only
unpacks a second stage installer into windows\temp. The second stage installer
unpacks some more files and when it arrives at 99% it broadcasts about 600
"LOGO_MSG_LOGOSTATUS_30" messages. But the first stage installer is still active
with a hidden window and it's message loop contains PeekMessage interleaved with
WaitForSingleObject on the second process with a 100ms timeout. That gives the
60s delay. I don't know yet how it works under Windows and what Wine is doing
incorrectly.

A workaround is to start the second-stage installer from windows\temp - that way
there is no first-stage installer window.
