CCH® ProSystem fx® Engagement or Workpaper Manager: Currently supported versions

In order to ensure the highest quality support and product experience, we have modified our policy on prior version support as outlined below:  

CCH ProSystem fx Engagement or Workpaper Manager is only supported on the current version and the two previous versions.
  • Since these products are released annually, this means the current version and two previous years.  
 For this purpose, support is defined in two parts:
  • Technical Compatibility
    • CCH will not provide software upgrades or the annual Tax Grouping Updates for software versions outside the support window.  
    • In addition, older versions will not be tested with new technologies, other CCH products, and third party software.
  • Customer Support
    • Our customer support representatives may not be able to diagnose or solve issues related to unsupported versions of Engagement or Workpaper Manager. 
    • We highly recommend that firms stay current with their software updates.  
    • This will allow firms to take advantage of improved usability, functionality, integration and third party compatibility.

Below is our version support timeline. Please be sure to review this policy and upgrade to a supported version if necessary:
