Solution

If you are running Microsoft Windows Vista or higher, you must run NI Update Service as an administrator.  Windows defines an administrator account as "a user account that lets you make changes that will affect other users." Installing new versions of NI software falls under this category.

Complete the following steps to elevate NI Update Service to run as an administrator: 
1.  Close NI Update Service.
2.  Run NI Update Service as an administrator: 
   a. Navigate to NI Update Service from Start»All Programs»National Instruments»NI Update Service.
   b. Right-click NI Update Service 
   c. Select Run as administrator  NI Update Service should now run as expected.  It will download and install available updates.

If you are still receiving errors, manually uninstall the Update Service via NI Package Manager. Then re-download Update Service from ni.com. Verify that your current and target versions of the software are compatible with your operating system, as errors often come from incompatible versions of operating systems and software.

If these steps do not work, please try the steps listed in Knowledge Base 5C8FQ2CZ: NI Update Service Freezes When Checking for New Version. This Knowledge Base article discusses the situation where the NI Update Service appears to pause on the "Checking for new versions" state.

If none of the above steps work, un-installing and re-installing all NI Software, including NI Update Service, can solve the issue : Uninstall National Instruments Software or Drivers Using NI Package Manager.
