I just updated to the 2014R2SP2HP1 version released yesterday, and found the windows client was extremely slow to upgrade. It wasn't just one step that took awhile, every stage just seemed to take forever... all told it took close to 25 minutes to install. My machine is a 3ghz quad-core with 16GB RAM and an SSD; most software installs very quickly. This was just an auto-update from the the previous 14.2.2 version from April.

Anyone else seeing this? Any idea why this release is so slow to install?
