Version 9.0.0 does have some bugs and security holes-which clearly doesn’t bother our IT guys too much or they would have a more up to date version. Our IT department is deploying new Windows 7 Enterprise boxes and I get to go behind them and install Acrobat 9 Pro. Officially they ended support as of June 26, 2013. Unfortunately, Adobe has scrubbed their website of any updates for their software because this version is too old. At my work, we use the full version of Adobe Acrobat 9 Professional.
