While configuring the SharePoint extensions on a MOSS 2007 instance, you hit an error:
TF255481: The following solution could not be upgraded in SharePoint Products: TswaWebPartCollection.wsp. The error is: Solution "tswawebpartcollection.wsp" is not deployed. To upgrade the solution in the configuration database, omit the -time, -immediate, and -local flags. To then deploy to the front end, use the deploy solution command.
Note: on a SharePoint 2010 instance, the configuration wizard throws the following message:
TF205021: A feature could not be activated in the following Web application: http://<server name>/. The feature is Tswa. This feature is part of the following solution: TswaWebPartCollection.wsp. Without this feature, project dashboards will not function correctly. Verify that the solution had been deployed to the SharePoint farm, and that the feature has been deployed in the SharePoint Central Administration.
