Additional to Sarmistha's reply, please carefully review the patch level in your Microsoft Project carefully as per the release notes. It is very important that you follow the requirements of the patch version.
Supported versions for your release (14.3) are Microsoft Project 2010 SP2, 2013 (only Legacy driver), and 2013 Service Pack 1 (only New driver). NO patches should be installed.
I am posting the following for when you decide to upgrade or for other community members that might be interested, but starting 14.4 and later, please check this KB article for supported patch levels: How do Microsoft Project monthly patches impact CA PPM?
Regarding SaaS and Single Sign On, you should have no issues but you will need to open the projects using the Open in Scheduler > Open in Microsoft Project option.
