Acrobat DC Update 15.006.30355 fails

If I try to update Acrobat DC manually, I get a message stating "The feature you are trying to use is on a network resource that is unavailable. Click OK to try again, or enter an alternate path to a folder containing the installation package 'AcroPro.msi' in the box below.'

The default path is C:\_SMSTaskSequence\Packages\0NE006EC\

If I try to allow the corporate software updater to work, it simply fails.

I am on a corporate network using Win7.

Any thoughts on how to get this to work?
