Software Deployment

Can I politely suggest that you continue your reading about MSI/Windows Installer technology? An MSI is intrinsicly able to reverse its actions: you don't need another one to do that.

To uninstall silently, you need to add the relevant switch to a command line, e.g.

MSIExec /X [path_to_and_name_of_MSI] /QN
or
MSIExec /X [ProductCode] /QN

Have a look at the Windows Installer help file MSI.CHM which will have been installed with your authoring tool. Search for '/Q' and select the third topic found 'Command Line Options'.

If you want that to happen when the MSI is double-clicked, you need to edit the 'UninstallString' entry in the registry to add the switch. That entry is stored at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\[ProductCode]

Hi VBScab,
Thanks for the information.
Client requirement is, we need to create a negative msi for Silent Uninstallation for the positive msi the client gives us.
For ex: Symantec antivirus.

Hoping for the Sweetfull response.

Tell the client (politely, of course) that they need to research Windows Installer. They evidently know nothing about it.

Send them my way: I'll put them straight. At my normal daily rate, of course.

avherur,

I think you've missed the point. "An MSI is intrinsicly able to reverse its actions: you don't need another one to do that."

If you have an MSI file - "app.msi" - then to install silently you would execute the command:

msiexec /i app.msi /qn

If the MSI file is already installed, and you wish to remove it from a machine then you execute (As VBScab stated):

msiexec /x app.msi /qn

Or use the [Product Code] - as also stated above.

It appears that your client does not understand Windows Installer technology.
I suggest you have a look at the help file (as suggested previously), and perform some of your own testing.

Hope this clears things up,

Shed light on the msiexec command line or what else?
