IV16294: WHEN TRYING TO UPGRADE NT AGENT FROM 6.2.2FP2 TO FP4 A POPUP IS EMITTED "ANOTHER VERSION OF THIS PRODUCT IS ALREADY INSTALLED.."

IBM Tivoli Monitoring 6.2.2 Fix Pack 9 (6.2.2-TIV-ITM-FP0009)

APAR status

• Closed as program error.

Error description

• When trying to upgrade NT agent from 6.2.2FP2 to FP4 customer
  sees popup "Another version of this product is already
  installed. Installation of this version cannot continue. To
  configure or remove the existing version of this product, use
  Add/Remove Programs on the Control Panel. {GUID}." This may
  also occur on other upgrades of other agents within the same
  GUID family.
  
  
  Customer installed initial version of the NT agent locally and
  left the install directories around. The Microsoft Installer
  finds this installation and issues the above popup.
  
  
  Recreate Instructions:
  This error cannot be recreated on many machines, but it is
  solid on those that demonstrated the problem.
  
  1. Copy the NT Agent locally to the C: drive or other local
  drive
  2. Install the NT agent from that drive in GUI mode.
  3. Use tacmd updateagent to attempt to upgrade 6.2.2 FP2 to
  6.2.2 FP4 or later.
  
  The deploy may fail or hang. Use taskkill /IM setup.exe /T to
  kill the hung setup.exe.
  On a system with the patch installed, the install will run to
  completion.
  

Local fix

• Search the registry for HKEY_CLASSES_ROOT\Installer\Products for
  SourceList. Then open the Net key under SourceList. Use the name
  data pairs to verify if they are part of ITM. When they are
  found to be part of ITM delete or rename the directory so it
  cannot be found from the registry. Either way works. Once this
  is done, rerun the remote deploy to the target system.
  

Problem summary

• When upgrading Windows OS agent from version 6.2.2 Fix Pack 2 to
  6.2.2 Fix Pack 4, a popup displays indicating the product is
  already installed.
  
  
  On Windows, the IBM Tivoli Monitoring installer may become
  confused when there are leftover files and registry settings
  from previous installations. As a result, the installer
  generates a popup, "Another version of this product is already
  installed. Installation of this version cannot continue. To
  configure or remove the existing version of this product, use
  Add/Remove Programs on the Control Panel. {GUID}". The remote
  deploy commands run this installer in silent (non-interactive)
  mode, so this interactive popup results in a failure to complete
  the remote installation.
  

Problem conclusion

• Prior to running the installer, the remote deploy command now
  cleans up leftover settings from previous installations allowing
  the installation to proceed.
