Re: Issue with the addon

Hi,

Please check with below SAP notes:

819501 - How to clean client after corrupt installation of
add-on(s)

• An installation of an add-on or of all add-ons failed. As a result, the
  installation process of the add-ons will not start, even though they are
  assigned to the company in the add-on administration. No error message
  appears.
  
  OR

• The following message appears when initializing an add-on: "Add-On XX Add-On
  installation failed because another version is alreadyinstalled. Upgrade Common
  DB".
  
  OR

• A user has accidentially uninstalled one or several add-ons using Add/Remove
  Programs on the Microsoft Windows Control Panel. As a result, the installation
  process of the add-ons will not start, even though they are assigned to the
  company in the add-on administration. No error message appears.
  
  If one of
  these symptom descriptions fit to your scenario, follow the steps described
  below.

• Start SAP Business One. Log on to the appropriate company.

• Choose 'Administration' -> 'Add-ons' -> 'Add-on
  Administration'.

• Remove the add-on(s) from the company by marking them and clicking the left
  arrow button.

• Choose 'OK'.

• Close SAP Business One.

• In Microsoft Windows, choose 'Start' -> 'Control Panel' -> 'Add or
  Remove Programs'.

• Check if any SAP Business One add-on(s) are displayed in the list.

• If an add-on is included, uninstall it by choosing 'Remove'.

• Using Windows Explorer, locate to the add-ons installation folder. Depending
  on the different versions of SAP Business One, the default installation folder
  is 'C:\Program Files\SAP Manage\SAP Business One\AddOns\sap' or 'C:\Program
  Files\SAP\SAP Business One\AddOns\sap'.If you chose a different folder during
  the installation process, locate that folder. Delete all subfolders (folders
  named like the add-ons) and, if present, the "_common" folder (which contains
  the framework for add-ons).

• Locate to the SAP Business One installation folder. The default installation
  folder is 'C:\Program Files\SAP Manage\SAP Business One' or 'C:\Program
  Files\SAP\SAP Business One'. If you chose a different folder during the
  installation process, locate that folder.

• Delete these files: 'AddOnsInstall.sbo' and
  'AddOnsLocalRegistration.sbo'

• Start SAP Business One.

• Log on to the appropriate company.

• Choose 'Administration' -> 'Add-ons' -> 'Add-on
  Administration'.

• Reassign the add-on(s) to the company.

• Choose 'OK'.

• Restart SAP Business One.
