The NWC2 install programs use NSIS CopyFiles instruction with the /SILENT 
directive, which calls the Windows Shell function SHFileOperation with the 
operation set to FO_COPY. In Windows, this operation can be used to replace an 
existing file. In Wine, this operation will fail when the target file exists.

The exact cause can be found here:

[CODE]
if (SHNotifyCopyFileW(entryToCopy->szFullPath, fileDest->szFullPath, TRUE))
[/CODE]

By setting the parameter "bFailIfExists" to true, the file copy operation will 
fail when the target file exists.
