Hi

We have developed an MSI pacakge for WMP 10 through EDP. In our customized network we can able to silently install or uninstall MSI packages.

This particular package installs fine. It is displayed in the Add/Remove programs as a windows update. But after the silent uninstall the package doesn't get removed. ie it doesn't get rolled back to WMP 9.
But on manually clicking the Remove button from the Add/Remove programs, the package gets removed and rolls back to WMP 9.

So how do we implement the same uninstall unattended. ope i am clear.

THanks in advance

How are you doing your silent uninstall? If you have some utility initiating that silent uninstall, I'd look into exactly how it's doing it.

Hi

We have an interface from where we can allocate and dealloacate applications to a workstation on a network. When we do the above, from what I know is it gets updated in an .ini file corresponding to the workstation in the server. When the workstation is restarted, an agent starts running looking in the .ini file for installing or uninstalling applications. So when WMP 10 is deallocated and the corresponding workstation restarted, the agent starts uninstalling the WMP 10. At that time it is not being removed.

There are also some uninstall commands which can be given in a package.ini file which I'm not sure of.

I've taken out the command line which will ask the query that Do you want restore to the previous existing version of WMP. But I do not know how to incorporate this to do the same during the silent install.

Hope i'm clear.

Thanks

Hi,

Try this!!!

If you are using Package.ini to install and uninstall..try following steps.

in the ini i hope u will be seeing

[General]
Name=..........

[Common]
...............

1. Find the GUID for the package example Package code : {7DA49652-81FC-407F-AC54-F0C43E798B01} which you can find under summary.

2. Edit your ini to

[General]
Name=..........
UNINSTALL={7DA49652-81FC-407F-AC54-F0C43E798B01}

[Common]
...............

it should work.

If you want to obtain the same result as by "Add/Remove programs ".
It is enough to recover the value contained in key "UninstallString" or "QuietUninstallString" being located in "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\YourApplication" and to use it in the script of desinstallation. :o)

Best regards
