Updated Oct 19, 2018

  • TestStand

Issue Details

  • I have one version of TestStand installed, I would like to install another version as well. I would like to know the following:
  1. Can I have more than one version of TestStand installed?
  2. How do I switch between different installed versions? 
  • I have multiple versions of TestStand installed. When I try to launch the TestStand Sequence Editor, I get the error below, or nothing happens.


Question 1 and 2 are answered below:
  1. Yes, it is possible to have multiple versions of TestStand installed. However, only one version of TestStand can be active and run at any given time.
  2. You select the version you wish to run by making it active in TestStand Version Selector tool (see picture below). If you have 32-bit and 64-bit versions of TestStand installed for the same year, ensure they are the same version and one isn't a SP1 patch.

You can launch TestStand Version Selector in the following ways:
  • (Windows 8.1) Click the NI Launcher tile on the Start screen and select TestStand»TestStand Version Selector.
  • (Windows 10 or 7) Start»All Programs»National Instruments»TestStand»TestStand Version Selector.
  • Run C:\<Program Files>\National Instruments\Shared\TestStand Version Selector\TSVerSelect.exe.

The error message is addressed below:

This issue can be fixed by opening the TestStand Version Selector and making the desired version active. This error message is the result of attempting to open a version of TestStand that is not the currently active version. The error message indicates which version is currently active and which version you are trying to open. In this case, we are trying to open TestStand 17.0.0 while Teststand 4.2.1 is active.

Additional Information

  • For more information about what happens when a specific TestStand version is made active, please see TestStand Version Selector.

  • With the release of TestStand 3.1, the TestStand Version Selector was introduced to facilitate having multiple versions of TestStand installed on a computer. See TestStand 3.1 Release Notes for more information.
