Files with the ’.wsp’ are SharePoint 2007 solutions that can be used to install software additions in WSS 2007 and MOSS.
To install a new solution in SharePoint , follow the next steps:
1 - Copy the .wsp file to the SharePoint server
2 - Open a DOS prompt (Start – Execute – cmd). Navigate to the directory of the SharePoint administration tool STSADM.EXE, normally found at "c:\program files\common files\microsoft shared\web server extension\12\bin\" for a SharePoint installation in English
3 - Execute the following command in the dos prompt:
stsadm.exe –o addsolution –filename SPSProfessional.Solution.Name.wsp
Using absolute path:
c:\program files\common files\microsoft shared\web server extensions\12\bin\stsadm.exe –o addsolution –filename SPSProfessional.Solution.Name.wsp
To install a new version of the Solution without having to uninstall the previous one, use the syntax:
stsadm.exe –o addsolution –filename SPSProfessional.Solution.Name.wsp -force
4 - Go to SharePoint Central Administration, open the "Operations" tab and use the "Solution management" link under the section "Global Configuration"
5 – On the "Solution Management" page there is a list of the installed Solutions, together with their status
6 - Click on the name of the Solution for additional information
7 - Use the "Deploy Solution" button to activate the Solution in the SharePoint servers. The Deploy page displays the configuration
8 - Choose the correct configuration for your server and deploy the Solution. If SharePoint is using a Farm configuration, the Solution will install the software in all the servers in the Farm
9 - The Solution Management confirms the Solution has been deployed (Status Deployed)
