When building in Visual Studio 2005 I encountered the problem that the downloads of pthreads and howl didn't succeed. They got as far as extracting a file called "[Content]" and then stopping. I added an extra section at the end of util.vbs/UnCompress like this to resolve it: If FSO.FileExists(DestFolder & "[Content]")Then Set MyFile = fso.CreateTextFile(UtilsDir & batname, True) MyFile.WriteLine("@" & quote & UtilsDir & "7za.exe" & quote & " x " & quote & DestFolder & "[Content]" & quote & " -y -o" & quote & DestFolder & quote ) MyFile.Close Set oExec = WshShell.Exec(UtilsDir & batname) Do WScript.Echo OExec.StdOut.ReadLine() Loop While Not OExec.StdOut.atEndOfStream WScript.Sleep(500) FSO.DeleteFile DestFolder & "[Content]",true End If Make sense?
