    *Starting with release 5.541.1023 (5.541.1023), Drafting Assistant installation consists of two parts:

    1. Installation framework installed into the %ProgramFiles(x86)%\Thomson Reuters\TRIAD folder and providing core services for add-in startup and hosting product binaries
    2. Product binaries installed into the%LocalAppData%\TRIAD folder and containing business logic

    The version numbering scheme includes a number for the installation framework, followed by the version number for the product binaries in parentheses. The product binaries contain business logic that can be updated more often than the installation framework. Product binaries are hosted by the installation framework that precedes the product binaries version. Therefore, the product binaries version number will be the same or newer than that framework version number. Product binaries can also be updated automatically without reinstalling Drafting Assistant.
