Version 9.0 brings significant changes to memoQ's system requirements. So that we are able to concentrate our efforts more efficiently on improving our product, we are letting go of supporting 32-bit installations. Also, for improved user experience and security, memoQ 9.0 requires version 4.7.2 of the Microsoft .NET Framework.
Also, project managers will need to upgrade their memoQ desktop app to be able to manage projects on memoQ TMSs of version 9.0. But the good news is that all minor versions of memoQ 9 project manager edition will be fully compatible with all minor versions of memoQ TMS 9!
