To answer your basic question, yes, you could. I don't think you can just unzip a .zip file from a custom action because I don't think there is a public unzip API in Windows [1]. You would have to include an unzip utility in your package that got installed before the custom action ran.
However, you could package your .zip file as a self-extracting executable and then run it as a custom action from the MSI. The MSI package itself could include the shortcuts and such. [1] But it can obviously be done since you can extract files from a .zip file using Explorer. > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of > Daniel Goldman > Sent: Friday, June 30, 2006 4:17 PM > To: wix-users@lists.sourceforge.net > Cc: [EMAIL PROTECTED] > Subject: Re: [WiX-users] customaction runs unzip? > > I appreciate your responding, but it doesn't answer my simple > question.
