During the installation of the ArcWeb Toolbar, if the installation program adds the .NET Framework, returning to the toolbar installation may display the following error:"Error 1722. There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor."
A change in the .NET support availability in ArcGIS prior to installing the ArcWeb Toolbar causes this problem. (The ArcGIS .NET support availability can be changed if the ArcGIS setup is run and the ArcGIS installation is modified.)
