Please note that we do not specifically code or test Internal Audit for Citrix/VDI compatibility, however versions 4.1 and later contain a configuration option to make the application more Citrix-friendly. 

This option is turned off by default, and so the first time multiple users access the application they will see an error like this (caused by a file sharing violation):

message:   I/O error during "CreateFile (open)" operation for 
file "C:\Users\[username]\AppData\Local\Vision\PentanaPRD\LocalData\Vision.fdb"
Error while trying to open file

To enable the option, the <Pentana.Tng.Agent> section of the vision.exe.config file should contain the following lines:

<Pentana.Tng.Agent>
<add key="IsVirtualized" value="true" />
<add key="VirtualizedServerListeners" value="10" /> <!--or what ever works for the given number of users) -->
</Pentana.Tng.Agent>

Note that later versions of this file do not contain a <Pentana.Tng.Agent> section, in which case:

• Ensure the file has this line under <ConfigSections> (normally it will):

  <section name="Pentana.Tng.Agent" type="System.Configuration.DictionarySectionHandler"/>

• Copy the entire <Pentana.Tng.Agent> section shown in the section above into the file

Notes on limitations of functionality

As the application is designed for local deployment, running under Citrix can make some features non-useful (e.g. checkout).

If the user's Windows profile is not persisted between sessions then:

• Deploying the client via ClickOnce may will cause a delay to each start, because the client will be downloaded each time the user launches Internal Audit
• Any data that gets checked out or reserved will be lost
• Certain settings (e.g. favourites for views) will be lost
