I am trying to unzip a file using Execute Process task but everytime I execute my application, a new window explorer gets open with source specific path defined in WinZip. I Jus want to execeute Process Task with unzipping the file and avoid this explorer window to get open. Please suggest a solution. I have tried performing with Execute Process Task and Script Task, in both the options I am facing the same issue (a new explorer window get open) this instance remains open. I want this explorer instance not get generated. 1st Method: Execute Process Task Expression Parameters: winzip32 -min -e -stestpassword ProductInfo.zip ProductInfo.txt 1. Arguments: "-min -e -s" + @[User::varPkgZipFilePassword] + " " + @[User::varPkgCurrentProductLineFileName] 2. Executable: @[User::varPkgZipExecutableLocation] 3. WorkingDirectory: @[User::varPkgSourceFilePath] 2nd Method: Scritp Task code snippet sa follows: Public Class ScriptMain Public Sub Main() Dim varCmdStr As String = Dts.Variables("varPkgZipExecutableLocation").Value.ToString() + " -min -e -s" + _ Dts.Variables("varPkgZipFilePassword").Value.ToString() + " " + _ Dts.Variables("varPkgCurrentProductLineFileName").Value.ToString() + " " + _ Dts.Variables("varPkgSourceFilePath").Value.ToString() MsgBox(varCmdStr) Shell(varCmdStr, AppWinStyle.Hide, True) Dts.TaskResult = Dts.Results.Success End Sub End Class

AFAIK winzip32is a GUI app, so you get the window. Use a different utility or its command line counterpart and you will be all set. An example using 7zip: http://www.ssisguru.com/2009/10/unzip-and-zip-files-using-ssis.html Arthur My Blog

If you want to unzip via a Script Task it's better (personal opinion) to use the Visual J# Redistributable Packages: http://microsoft-ssis.blogspot.com/2011/01/unzip-files-with-ssis.html Please mark the post as answered if it answers your question | My SSIS Blog: http://microsoft-ssis.blogspot.com

In the Execute Process Task, change the window style to hidden. <img src="http://lookpic.com/c1/i2/2485/hFeZc6EI.jpeg"></img> Chaos, Disorder and Panic ... my work is done here!

Previously while development we used 7z only, we need to change in to winzip, because as per our company policy we should not use 7z
