Starting with the Vault 2018 release our intention is to provide only 64-bit compatible client and server installers, support will not change for previous Vault releases and will not impact current forward compatibility support, providing a period for customers to plan operating system upgrades and software roll outs.
Our research to date indicates the impact of this decision will affect only a small fraction of our installed base, but if you do have concerns around this change please reach out to your Autodesk Partner or sales representative for information on what options you have and on how this decision may impact your current software strategies.
Please note as a matter of practicality, ongoing support will be available for those using Office 32-bit products on 64-bit operating systems.
