Error 1723 when installing Acrobat Pro 11.0.19 upgrade?

[johnb96464089]

Earlier today I was upgrading Acrobat Pro on multiple standalone Windows 7 64-bit computers to version 11.0.19 from 11.0.18.  It worked perfectly on all machines except one.  On that machine I kept getting the following message: "Error 1723: There is a problem with this Windows installer package.  A DLL required for this install to complete could not be run.  Contact your support personnel or package vendor.  Action ISSetupFilesExtract, entry: SFStartupEx, library: C:\Windows\system32\config\SYSTEM~1\AppData\Local\Temp\MSI2F2A.tmp."  Does anyone have any suggestions on how to fix this issue?

are you manually instaling the updates from  http://www.adobe.com/downloads/updates/

if so, make sure you have read/write permissions on your temp folder and empty it.
