Troubleshooting - Lexacom will not update


The Lexacom software has advised that there is an update ready to be applied to your installation; when the Lexacom application is restarted the update fails to install.


There can be many reasons for an update failing to install. The main causes are normally due to folder permissions to the currently logged in computer user or Anti-Virus software blocking access to certain essential applications.


You or your computer administrator will need to check that Full Control permissions has been given to all users over the following local folders:

Windows XP

  • C:\Documents and settings\All Users\Application Data\Aprobrium
  • C:\Program Files\Aprobrium

Windows Vista / Windows 7 32bit

  • C:\ProgramData\Aprobrium
  • C:\Program Files\Aprobrium

Windows Vista / Windows 7 64bit

  • C:\ProgramData\Aprobrium
  • C:\Program Files (x86)\Aprobrium


In general it is recommended to give the Users or Authenticated Users groups full control to these folders; if using custom permissions groups please ensure that all groups containin Lexacom users are given the appropriate permissions.


If using or earlier, please ensure that your antivirus is not configured to block access to the unrar.exe utility. This application is used by these versions to extract the update from the compressed files they are delivered in, so that they can be installed into your program folders. In some cases antivirus or endpoint protection may block access to this utility.


If using and later updates deploy the Lexacom update as an executable (clientupate.exe) which should delete and extract the update if the user has permission to modify the contents of the Lexacom program files folder.


If using the additional Lexacom Echo service, updates to Lexacom Echo may include Microsoft Visual C++ Redistributable components that will require Administrator rights over the PC to install; if this fails to install, please speak with your general system administrator or IT support for admin rights.
