📌 Problem
When installing or starting LP360, a message may appear indicating that the Microsoft Visual C++ Redistributable is not installed, even though one or more Visual C++ Redistributables already appear installed on the system.
This message may prevent LP360 from launching or completing installation.
🔍 Root Cause
This behavior is typically caused by a detection mismatch, not by a missing dependency.
LP360 relies on Microsoft’s shared Visual C++ Redistributables, which:
- Are installed system-wide and shared by many applications
- Support multiple Visual Studio versions with a single runtime
- Are updated in place rather than installed side-by-side
In some cases, Windows or an installer may not correctly detect an existing Visual C++ Redistributable due to architecture differences (x64 vs x86), registry inconsistencies, or partial installations. Even when the runtime is present and functional, it may still be reported as missing.
đź§ What is the Microsoft Visual C++ Redistributable?
The Microsoft Visual C++ Redistributable provides runtime libraries required to run applications built with Microsoft Visual C++.
LP360 does not include these runtime libraries directly. Instead, it depends on the Visual C++ Redistributables installed on the system. A newer supported redistributable always satisfies the requirements of software built against older versions in the same v14 family.
Because these runtimes are shared and updated in place, the presence of the required files does not always align with what an installer’s detection logic expects to find.
âś… Probable Resolutions
Install both x64 and x86 Visual C++ Redistributables
Even on 64-bit versions of Windows, some components require the 32-bit (x86) runtime.
Download and install both the x64 and x86 Visual C++ Redistributables from Microsoft:
Download Visual C++ Redistributables from Microsoft
Repair existing Visual C++ Redistributable installations
If the redistributables already appear installed, performing a repair often resolves detection issues.
Open Apps & Features (or Programs and Features), locate the Visual C++ Redistributables, and choose Modify or Change, then select Repair. Repeat for both x64 and x86 entries if present.
Retry the LP360 installation or launch
After completing the steps above, restart Windows if prompted, then retry installing or launching LP360.
Re-run the Visual C++ Repair immediately before installing LP360
If the installer still reports the Visual C++ Redistributable as missing after completing the steps above, re-running the redistributable repair immediately before installing LP360 can resolve the issue.
Download the latest Visual C++ Redistributables from Microsoft, then run the x64 and x86 installers and choose Repair. Without restarting Windows, immediately run the LP360 installer using Run as administrator.
This process refreshes system registration information that the installer checks, without changing or downgrading any installed components.
Run the LP360 Install from an elevated command prompt
There may be something else going on with your machine configuration that is interfering with the proper installation of LP360. From an elevated Command Prompt (right-click on Command Prompt and select "Run as Administrator"), please run the following command using the full path to where you have the MSI and writing the log file to a directory that you can access.
msiexec /i "LP360_v2025.2.246.0.msi" /L*v "log64.txt"
Contact Support to send the log file that gets generated.
📚 Additional Notes
You do not need to uninstall newer Visual C++ Redistributables to use LP360. Newer supported redistributables fully satisfy LP360’s runtime requirements.
In most cases, simply ensuring that both x64 and x86 redistributables are installed and repaired resolves the issue.
If all steps above have been completed and the installer still reports a missing redistributable, the system requirements are typically already met and further runtime changes are not required.
