Error Upgrading to 5.5U2

Trying to upgrade to 5.5U2 form 5.5U1 and having several issues.

First, when I click on the web client install button I receive "file not found.. E:\\vSphere-WebClient\Vmware-WebClient.exe"

Second, when I navigate to that path manually and try to run the exe I get the error "This app can't be run on your PC"

Host os is Win2k12 R2 Datacenter. Has anyone else seen similar issues or had success updating the WebClient?

Thanks
