9. The registration service is unregistered with VCM.
10. An attempt is made to contact the simple install using DCOM.
If this action succeeds, this step in the process is finished.
If the process fails on any of the actions, the simple installer job enters the rollback state. All modules are
uninstalled, all files are removed, and the registry is purged. In this state, the debug event files are not
deleted on the target machine. The file might contain useful information about the error.
Install Module Installer
The module installer action manages the installation of the product modules when you install the VCM
Agent on target Windows machines.
The installer is called on to terminate the Windows Agent installation process when an inspection job is
canceled. It can update the installation infrastructure. The module installer completely removes the
remainder of the VCM files during the uninstallation process.
1. Determine if the module installer component was deployed. If it exists, a check is preformed to see if it
needs to be upgraded.
2. If the module installer needs to be installed, the following actions are run.
n A connection is made to the simple installer.
n The runtime install lock is updated.
n The module installer is deployed and run by the simple installer.
3. Determine if any installation infrastructure modules must be upgraded.
Outdated components are listed and upgraded.
4. If a component of the installation infrastructure, other than the module installer, must be updated, the
following actions run.
n A connection is made to the module installer.
n The registration service is copied if it is not present on the target Windows machine.
n All infrastructure modules that must be updated are copied to the target machine.
n A call is made to the module installer to install the installation infrastructure modules. This call is
received and delegated to the registration service to perform the action.
n A connection is made to the simple installer.
n The runtime install lock is updated.
n The module installer is pushed out and run by the simple installer.
5. Any installation infrastructure modules that must be removed are removed.
If an action fails at any point, the changes are rolled back and the installation fails.
Resolve All Versions of Modules Based on Highest Version Number
The resolve all versions of modules action evaluates the modules to be installed against those already on
the target Windows machine and determines what must be installed for the VCM Agent.
The action uses the resolve highest version modules resolution algorithm.
