When using the Process Modeler in Internet Explorer, users experience the following behavior:
The following screenshot shows the behavior:
In order for the Process Modeler to render correctly, Appian utilizes a DLL file named vgx.dll, used explicitly for vector graphics rendering.
In response to CVE-2014-1776, many system administrators unregister this DLL from end users' machines. This results in rendering issues of the Process Modeler in Internet Explorer.
The threat has been mitigated since its discovery, so users should feel comfortable enabling that DLL across their machines by performing the following steps:
regsvr32 "%CommonProgramFiles%\Microsoft Shared\VGX\vgx.dll"
regsvr32 "%CommonProgramFiles(x86)%\Microsoft Shared\VGX\vgx.dll"
This article applies to all versions of Appian using Internet Explorer as a web browser.
