What Does “BFT Tool Failed to Check for New Version” Mean?

The “BFT Tool Failed to Check for New Version” error means the BFT Tool cannot connect to its online update server when starting on Windows. The tool checks for a newer version through an internet connection. If the network is unstable or Windows Firewall or a proxy blocks the connection, this message appears. It does not always mean the BFT Tool is damaged or corrupted; the problem is often related to the update connection.

Why Does the BFT Tool Fail to check for a new version?

Internet Connection Problem

BFT Tool checks its update service through the internet when it starts. If your connection is offline, slow, or unstable, the tool may fail to contact the server and show this version-check error.

BFT Update Server Unavailable

The problem may come from the BFT update server itself. If the server is temporarily down, busy, or not responding, BFT Tool cannot verify whether a newer version is available.

Windows Firewall Blocking the Tool

Windows Firewall can restrict BFT Tool from making network connections. If the application is blocked, it may not reach the update service even when your PC has a working internet connection.

Antivirus Interference

Third-party antivirus or security software may treat BFT Tool as an untrusted application and restrict its network access. This can prevent the tool from contacting its update server during startup.

Outdated or Damaged BFT Tool Files

An old, incomplete, or damaged BFT Tool package can cause startup and update-check problems. Missing or changed program files may stop the software from completing its normal version-check process.

Incorrect Windows Date and Time

Incorrect Windows date, time, or time zone can sometimes affect secure network connections. When system time is wrong, applications may have trouble communicating with online services correctly.

DNS or Network Restrictions

DNS problems, proxy settings, VPNs, or network restrictions can interfere with BFT Tool’s connection to its update service. Windows also notes that proxy and DNS issues can affect application connectivity.

How to Fix BFT Tool Failed to Check for New Version?

Internet Connection Problem

BFT Tool needs internet access to check its update service. A weak, disconnected, or unstable connection can stop this request. Test websites first, then reconnect Wi-Fi or try another network before launching BFT Tool again.

BFT Update Server Unavailable

Sometimes your PC is working normally, but the BFT update server is temporarily unavailable. In this case, the tool cannot complete its version check. Wait for the service to return and try opening BFT Tool again.

Windows Firewall Blocking the Tool

Windows Firewall can restrict an application from communicating through the network. If BFT Tool is blocked, add its trusted executable to Allow an app through the firewall instead of opening unnecessary ports.

Antivirus Interference

Third-party antivirus or Windows Security may restrict an unfamiliar BFT Tool executable. Check the security software’s blocked or quarantine list and verify whether BFT Tool has been prevented from running or accessing the network.

Outdated or Damaged BFT Tool Files

An old or incomplete BFT Tool package may cause problems during startup or version checking. Replace the existing files with a fresh, trusted copy and avoid mixing files from different BFT Tool versions.

DNS or Network Restrictions

DNS problems, proxy settings, or network restrictions can prevent BFT Tool from reaching its update service. Try flushing the DNS cache and checking Settings > Network & Internet > Proxy for unwanted manual settings.

How to Fix MSVCR100.dll or MSVCP100.dll Errors?

If BFT Tool shows an MSVCR100.dll or MSVCP100.dll missing error, install or reinstall the Microsoft Visual C++ 2010 Redistributable from Microsoft. Install the required x86 and x64 packages, then restart Windows and launch BFT Tool again. Microsoft provides the official Visual C++ 2010 Redistributable installers.

How to Find the Real Cause

Diagnostic Check	What It Tells You
Browser loads websites normally	Your basic internet connection is working, meaning the blockage is specific to the BFT Tool or its network access.
Disabling VPN / Proxy resolves the error	A VPN or custom proxy setting was interfering with or re-routing the update server connection.
Allowing the app through Firewall / Antivirus fixes it	Windows Firewall or your security software was actively blocking the tool.
Tool works on another network (e.g., Mobile Hotspot)	Your primary Wi-Fi or local network has specific DNS, proxy, or router filtering issues.
Installing missing runtimes (C++, .NET) fixes startup	Your system was missing essential Windows dependencies or runtime drivers.
Error persists across all networks and settings	The update server itself may be experiencing temporary downtime, or the tool version may be permanently restricted or banned.
