Windows Update uninstall problem by katanel

Posted bykatanel on Fri Feb 05 01:26:08 CST 2010 •

I hope I posted this in the right place.
I tried to uninstall an update using a C++ application I made. I use the
Windows Update Agent API create an IUpdateSession then an IUpdateInstaller I
set the update collection for the installer and then use the
IUpdateInstaller->Uninstall method but I get the 0x80240028 error message. I
understand that this means an uninstall can be started only by WSUS but is
there any way I to send a command to the WSUS to uninstall the update or to
"associate" my application with the WSUS server?
Thank you!

I observed that the IUpdateSession interface has an ClientApplicationID
property that should be set; does anybody know what is it used for? I didn't
set it because I'm not sure what value should it have.
May this be the problem?
Thank you!
