For customers who need to know what registry entries are affected by Prizm ActiveX Viewer, or just information about what Prizm Viewer sets up during the installation process, what details do we have?

Installation Levels

When Prizm Viewer is installed, there are two levels where it operates: 

1. Machine level: All components and settings that are shared across all users on the system.
2. User level: Only used for file associations. 

Machine Level Installation

Since Prizm Viewer currently does not support a user install mode, all components are installed in shared system directories. These include: 

System Folders

C:\Windows\SysWOW64\ (or C:\Windows\System32\ for 32bit OS
C:\Program Files (x86)\Accusoft\Prizm Viewer

Registry Locations

HKEY_LOCAL_MACHINE\SOFTWARE\AppDataLow\
HKEY_LOCAL_MACHINE\SOFTWARE\Classes

The settings stored in these locations are set once at installation and are never changed during the runtime of Prizm Viewer.  At runtime, the values from HKEY_LOCAL_MACHINE\SOFTWARE\Classes\ and HKEY_CURRENT_USER\SOFTWARE\Classes\ are combined into HKEY_CLASSES_ROOT, with the user-specific settings taking precedence.

Machine-Level Components and Registry Entries

When Prizm Viewer is initially installed, the following items is installed for all users.

File Associations Settings

For each extension installed or removed, settings are transferred between the following registry locations:

HKLM\SOFTWARE\MICROSOFT\Internet Explorer\Capabilities\FileAssociations

HKLM\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\Capabilities\FileAssociations.svg

Additional Notes

• The .svg extension requires special handling to avoid conflicts with Internet Explorer. Ensure the following registry key is removed rom the 64bit registry using the KEY_WOW64_64KEY flag:

  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Capabilities\FileAssociations.svg

• Some configurations, such as plug-in registry entries, may require custom applications to apply changes.
