What are LST_Helper2.exe Error Messages?

LST_Helper2.exe Runtime Errors

Runtime errors are LAN Speed Test errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EXE errors are triggered when LST_Helper2.exe is attempted to be loaded either when LAN Speed Test is starting up, or in some cases already running. Runtime errors are the most common form of EXE error you will encounter using LAN Speed Test.

In most cases, LST_Helper2.exe runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these LST_Helper2.exe error messages mean that LAN Speed Test was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, LAN Speed Test will be unable to start without resolving these errors.

Some of the most common LST_Helper2.exe errors include:

LST_Helper2.exe - Bad Image.
LST_Helper2.exe Application Error.
LST_Helper2.exe could not be found.
LST_Helper2.exe could not be installed.
LST_Helper2.exe could not be launched. Class not registered.
LST_Helper2.exe could not be started.

Error starting program: LST_Helper2.exe.
Faulting Application Path: LST_Helper2.exe.

System Error

The program can’t start because LST_Helper2.exe is missing from your computer. Try reinstalling the program to fix this problem.

Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

Finding the source of the LST_Helper2.exe error is key to properly resolving these errors. Although most of these EXE errors affecting LST_Helper2.exe will happen during startup, occasionally you will encounter a runtime error while using LST_Helper2. This can occur due to poor programming on behalf of Totusoft, Inc., conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of LST_Helper2.exe errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

How to Fix LST_Helper2.exe Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your LST_Helper2.exe issue. These troubleshooting steps are listed in the recommended order of execution.

Hit the Windows Start button
When you see the search box, type "System Restore" and press "ENTER".
In the search results, find and click System Restore.
Please enter the administrator password (if applicable / prompted).
Follow the steps in the System Restore Wizard to choose a relevant restore point.
Restore your computer to that backup image.

If the Step 1 fails to resolve the LST_Helper2.exe error, please proceed to the Step 2 below.

Step 3: Perform a Windows Update.

CAUTION : We strongly advise against downloading and copying LST_Helper2.exe to your appropriate Windows system directory. Totusoft typically does not release LAN Speed Test EXE files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing LST_Helper2.exe and all other EXE files for LAN Speed Test.
