[Bug 26176] New: JavaScript custom-actions not running?

http://bugs.winehq.org/show_bug.cgi?id=26176

Summary: JavaScript custom-actions not running?
           Product: Wine
           Version: 1.3.14
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: msi
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I have an MSI package that installs fine on Windows, but has a problem on Wine
1.2.2 and 1.3.14.

On a clean Ubuntu with Wine, it gives the error:
"A previous installation of Cogniview none was detected."

I have access to the people who develop this package, and we came to the
conclusion that it might be because some JavaScript custom actions are not
executed properly.

For example, the custom action "MakeInstalledName" definitely doesn't execute.

You can download the package that has the problem from:
http://download.cogniview.com/PDF2XL-Setup-Eval.msi

Note, that a *different* but similar package of the full product *works and
installs fine* (it has some custom actions that are different):
http://download.cogniview.com/PDF2XL-Setup-Full-4.10.msi

I tried running the package with full logs, something like:
msiexec /lv* log.txt /i ...
but the log output is very minimal and only gives me one line.

Any help will be greatly appreciated!
