Install AgilePoint Server. This error is rarely seen, but tends to be reproducible on machines where it does occur.
If you are installing AgilePoint Server and receive this error, run the AgilePoint Shared Components Installer (ComponentsInstaller.msi) located within your AgilePoint installation package. Depending on the AgilePoint Server edition (.NET 1.1 or .NET 2.0) you are installing, the ComponentsInstaller.msi file is located in one of the following folders:
...\Support\x64_Windows\Components
...\Support\x86_Windows\Components
After running the ComponentsInstaller.msi file you should then be able to install AgilePoint Server without encountering the above error.
