The error is shown due to a missing update for Universal C Runtime in Windows. Install the update using one of the following ways:

Solution 1

Download the update manually from Microsoft Download Center
Once the required update is installed, retry the Acrobat/Acrobat Reader installation.


You must be on Windows 7 Service Pack 1 (SP1) or higher to apply this update.

Solution 2

Use Windows update to update the OS automatically.
Retry Acrobat/Acrobat Reader installation, once all the available Windows updates are installed.

Solution 3

  1. Download Visual C++ Redistributable Packages for Visual Studio 2013 from Microsoft Download Center.

  2. If you're on a 64-bit machine navigate to the folder C:\Windows\SysWOW64\ else navigate to C:\Windows\System32, on a 32-bit machine.

    Note: If C:\Windows\SysWOW64 folder exists then you're on a 64-bit machine.

  3. Search for the file msvcr120.dll and msvcp120.dll, and rename both the files.
    Don't delete the files. If the Visual C++ redistributable (vcredist_x86.exe) package fails to install, you can rename the files back.

  4. Double click the downloaded Visual C++ redistributable (vcredist_x86.exe) package to install it. After the installation completes, check that msvcr120.dll and msvcp120.dll files are installed back. Once confirmed, you can delete the files that you renamed in step 3.
    Do not delete the latest installed msvcr120.dll and msvcp120.dll files.

  5. Install Acrobat/Acrobat Reader.
