Below is a screen shot I received in step 3 of 3 during the Adobe Acrobat Reader installer. In step 1, I had to choose my operating system, which is Windows 7.

enter image description here

Before clicking the "Install Now" button, I unchecked the "Yes" checkboxes to avoid advertisements.

I normally use Google's PDF viewer in gmail, but I'd like a reliable Windows PDF viewer. Is anyone aware of one that works and is free, or knows how to get Adobe's installer to work?

    Are you running the installer as an administrator? – Burgi May 8 '16 at 21:09

Solution to my specific problem:

Per @Ouroborus answer....

  1. I didn't have Google Desktop installed, so that wasn't it

  2. Deleted all sub-folders under C:\WINDOWS\Temp

  3. When the file downloaded, I chose Open, and right clicked, to "Run as Administrator" (per @Burgi)

Sounds like it was either #2 or #3 that solved it. Or a combination of both.


Update 'Adobe Reader XI (11.0.10)' could not be installed. Error code 1603.

Like most Windows applications, Acrobat and Reader use Microsoft Windows Installer technology for installing updates. If the update fails, you can get one of the following Microsoft Installer errors.


1603 A fatal error occurred during installation or #AdobeError#1603

Shut down Microsoft Office and all web browsers. Then, in Acrobat or Reader, choose Help > Check for Updates.
