Uninstalling CTE from Windows

Considerations

• The CTE Agent must be removed from the Windows host before the host is removed from the key manager with which it is registered.

• Database applications like DB2 and Oracle can lock the user space while they run. If the uninstall fails because a GuardPoint is in use, determine which applications are using the files in the GuardPoint and stop them. Then uninstall again.

Procedure

1. Stop any application from accessing files in the GuardPoint.

2. In the key manager with which this host is registered, do the following:

   • Decrypt any data you want to use after uninstall. After the CTE Agent software is removed, access to data is no longer controlled. If data was encrypted, it will remain encrypted. If decrypted or copied out of the GuardPoint, the data is visible as clear text.

     This decryption must be done on every GuardPoint on the host if you want to access all existing data on the host.

   • Make sure the Agent and System locks have been disabled for the host.

   • Thales recommends that you remove all GuardPoints from the host before you uninstall the CTE Agent.

   Do not remove the host from the key manager yet.

3. Log on to the host as with system administrator privileges.

4. Use one of the following methods to uninstall the CTE Agent:

   • Use the standard Windows Add/Remove program utility from the Control Panel to remove the CTE software.

   • If you installed the CTE Agent using the MSI file, you can uninstall it using the command line with:

     msiexec.exe /x <Installation_executable> /qn` command.
     

   For example:

       :::yaml
       msiexec.exe /x vee-fs-7.3.0-135-win64.msi /qn
   

5. Reboot the system when prompted.

6. Remove the host record from the key manager.
