There are a few different ways in which might present when it is unable to start -


  • Error 9006: The application version is less than the data file version (occurs when Ivo is unable to automatically execute an update)
  • Error 9001: The Ivo data file could not be found
  • Error 52: Bad file name of number
  • Nothing at all - An Ivo icon briefly appears on the taskbar and then disappears again



Error 9006: The application version is less than the data file version


Cause: Ivo has been updated, but the user's computer has not automatically updated.  The most likely cause of this issue is the user does not have the necessary Windows security privileges to install the update.


To resolve, a Windows administrator needs to manually install the update by executing the update file -


        <Ivo Data Location>\1024\Updates\Ivo_Upgrade_??????.exe



Errors 9001 and 52


These errors occur when Ivo is not able to find the Ivo data file in the 'Data Location' specified in the \ProgramData\1024\Ivo\Ivo.ini file


Following the steps below should resolve the issue.



For Users of Ivo


Is your computer connected to your organisation's network? Checking whether you can access the internet and email are a good indication. Also check your network cable (usually blue) or wireless connection to ensure you are connected.


Has any work been done on your IT infrastructure that could have affected Ivo, such as installing a new server or migrating data from location to another? If there is anything that has happened that could have affected Ivo, please be sure to inform us when you request support. It saves a lot of time.



For IT Support Providers


The "DataLocation" is stored in the Ivo.ini file located in "<ProgramData>\1024\Ivo" (Note, "ProgramData" is a hidden folder).  Ensure the DataLocation value is correct.  It can be a mapped drive or UNC value.


Setting permissions on the <ProgramData>\1024 folder to give any of these 'Modify' permission on the folder - Domain Users, or Authenticated Users, or Users, or Everyone - is beneficial because it will prevent the folder being "virtualised" as described below.



The Windows "VirtualStore"


Sometimes the Windows "VirtualStore" is active and prevents Ivo from correctly accessing the ProgramData and Program Files folders.


First, check if this the case by seeing if there is a "C:\Users\<User>\AppData\Local\VirtualStore\1024\" or "C:\Users\<User>\AppData\Local\VirtualStore\ProgramData\1024\" folder.  


Please note...

  • Folders, such as a "ProgramData" folder will be hidden so the "show hidden files" option should be switched on in Windows File Explorer.

  • The 'VirtualStore' folder may not exist at all, in which case it is probably not switched on.

However, if there are 1024 related folders in the VirtualStore then choose one of the following options;

  1. Turn the VirtualStore off completely by turning off User Account Control

  2. Disable the VirtualStore. In Windows 7 for example;
    1. From the Windows 7 Start Orb, do a search for Local Security Policy and select it.

    2. Expand Local Policies and click on Security Options. 

    3. On the right pane, scroll all the way to the bottom and you will find a setting called "User Account Control: Virtualize file and registry write failures to per-user locations" - double click on that setting and change it to Disabled. 

  3. Give users (eg. Domain Users, Machine Users, Authenticated Users or Everyone etc) 'Modify' permissions on the "C:\ProgramData\1024" and "C:\Program Files (x86)\1024" folders - this will essentially bypass the Virtual Store for those folders only.



Make sure you delete any 1024 and Ivo related files and folders in the VirtualStore folder, then either manually edit the "<ProgramData>\1024\Ivo\Ivo.ini" file with the correct "DataLocation" value, or reinstall Ivo.
