I've installed the add-on as administrator, but other users cannot see the add-on

Scenario (Are you affected)

• You run Windows Vista, Windows 7, or Windows server 2008
• You have User Access Control turned on
• You are not right-clicking on the SAP Business One icon and selecting Run as Administrator

Symptoms (One or more)

• Add-on does not appear as Installed for the user
• Add-on was already installed but users see the install-screen again
• Add-on fail during install/uninstall with an access denied error

How to Fix?

• Log in to the machine where the user is affected.
• Browse where the Business One application is installed (Example: C:\Program Files\SAP\SAP Business One)
• Select the file AddOnsLocalRegistration.sbo (If it exist)
• On the toolbar of the browser press the button 'Compatibility Files' to have visible the contents of the virtual folder
• Locate and delete the phantom files: (AddOnsInstall.sbo & AddOnsLocalRegistration.sbo)
• Add-ons will be now available for the user affected

How to avoid issues in the future (Select one)

• Always remember to run user as Administrator first time when an add-on is installed/upgraded/removed
• Turn off User Access Control (Not recommended by Microsoft)
• Alter permissions to C:\Program Files\SAP\SAP Business One to let everyone write this folder and sub-folder
