Error installing a new version of the Application Metering Plug-in - Error 1714

Products

• Inventory Solution

Issue/Introduction

While trying to upgrade the Application Metering Plug-in, you get MSI error message:

Error 1714

Environment

ITMS 7.x, 8.x

Cause

A registry key is left that causes the new Application Metering Plug-in installer to attempt removing the previous version.

Resolution

Use the following process to find and eliminate the registry key (the deletion of the registry key can be scripted once the path is known):

1. Go into regedit
2. Browse to the following location:
   HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products
3. Do a search under this key for "Metering".
4. Once the key is found that contains values for Application Metering, delete the key.
5. For scripting the deletion of this, here is an example (the numbered key may be different as each version of the Plug-in has a different hexidecimal value):
   reg query HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products\A64BFC04031DE2347BD701E036C9AB20
if %errorlevel% EQU 0 (
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products\A64BFC04031DE2347BD701E036C9AB20 /f
)
