Facing problem while upgrade process

Sep 8, 2011 at 7:17 AM

When i am trying to upgrade installed product using CodePlex SharePoint solution Installer it gives me following error:
Solution "xxxxxxxxxxx.wsp" is not deployed. It is upgraded in the configuration database. To deploy to the front end machines, use the Deploy method.

When i tried debugging the code, i found that code gives such error on following line:
solution.Upgrade(FileUtil.GetRootedPath(SolutionInfo.File), JobCmd.GetImmediateJobTime());

Is your solution listed in Central Admin Solution Management? What is its status there? Have you tried redeploying it from there?
