The entire process of installation/deployment of KWizCom WSP's is done automatically by the "SP-WSPsInstaller v1.0.01.ps1
" PowerShell script(included in every KWizCom product zip file). This script also upgrade your existing KWizCom products by checking if there is already an existing older version deployed. In such a case, the existing version will be automatically retracted and removed the old product version, and the newer product version will then be installed and deployed.
