What to do
Antivirus blocking the file
If your antivirus blocks the file, report this false positive to it and write to support at contact@fuzevpn.com.
Portable version
The portable version works without installation. Extract the whole folder, then start FuzeVPN, including from a USB stick. Connecting to the VPN requires administrator permission.
Windows permission
Accept the Windows permission prompt when it appears, then try again. If the message asks you to, quit FuzeVPN with “Quit FuzeVPN”, in the menu of its icon near the clock. Then reopen it and accept the prompt.
Standard Windows account
Portable version and standard Windows account: a PC administrator must accept the Windows prompt each time you connect. Installing FuzeVPN, which applies to the whole PC, also requires administrator rights. Once FuzeVPN is installed, a standard Windows account can connect to the VPN.
Installation in a protected folder
If FuzeVPN asks you to install it in a protected folder, run the official signed installer from the FuzeVPN for Windows page again. Take the recommended EXE file, choose “Repair”, then accept the Windows prompt.
x64 or ARM64 processor
A PC is either x64 or ARM64: the processor type is shown in the Windows system information. Uninstall the current version, then install the right one from the FuzeVPN for Windows page, which offers both.
FuzeVPN for WindowsWhich devices and browsers can I use FuzeVPN on?
Local VPN service unavailable
Quit FuzeVPN with “Quit FuzeVPN”, in the menu of its icon near the clock, then reopen it. Accept the Windows prompt if it appears. If FuzeVPN is finishing an operation, wait until it is done, then try again.
VPN status cannot be verified
Right after Windows starts, give FuzeVPN time to start its service. Then try the check again. If the status remains unknown, quit and reopen FuzeVPN.
Installation cannot be verified
Try the check again, then quit and reopen FuzeVPN. If the installation still cannot be verified, run the official signed installer from the FuzeVPN for Windows page again and choose “Repair”. Your preferences are kept.
Restart the PC
Is the local VPN service still unavailable, or can the VPN status or the installation still not be verified? Restart the PC, then try again.
Another Windows session
If the VPN is being used by another Windows session, open that session. Disconnect the VPN there, then choose “Quit FuzeVPN” in the menu of the icon near the clock. Then return to your session and try again.
FuzeVPN is already starting
If FuzeVPN does not open because it is already starting, wait for it to finish starting, then try again.
Reinstall FuzeVPN
If the message comes back, reinstall FuzeVPN with the official signed installer from the FuzeVPN for Windows page. Your preferences are kept, and a new device is added automatically at your next connection. If your device limit is reached, the app simply asks you to remove one.
Write to support
Write to support at contact@fuzevpn.com if the message asks you to or if the problem continues. Include the exact message, the time and the FuzeVPN version if it is visible. Add the Windows code if it is shown and, if possible, the FuzeVPN diagnostic report.
Why it happens
- Your antivirus is blocking the installation file. FuzeVPN’s Windows files are signed in the name of FuzeVPN: this is a false positive.
- The portable version starts without installation, from its extracted folder, including from a USB stick. Connecting to the VPN does, however, require administrator permission. The VPN engine, your data and the network components are also installed in Windows.
- The Windows permission prompt was not accepted. WireGuard or OpenVPN, the protocols that establish the VPN connection, need it, so Windows refuses the operation. With the portable version, a PC administrator must give this approval for the connection. If the refusal comes back, your Windows account’s rights or the PC’s security rules may be the cause.
- The OpenVPN component built into FuzeVPN could not be prepared on this PC. To prepare it, FuzeVPN needs your approval in the Windows prompt.
- FuzeVPN’s service folder does not pass the protected installation check: part of the installation is missing, or the VPN engine could not be prepared there.
- The installed version is made for a different processor type than the PC’s: x64 instead of ARM64, or the reverse. This message can appear during a FuzeVPN update.
- FuzeVPN’s VPN service on this PC is not responding: it is finishing another operation, it is still starting or it did not start.
- FuzeVPN cannot confirm the status of the VPN and its protections. Right after Windows starts, its service may not have finished starting.
- FuzeVPN cannot verify its installation on this PC: the check of its component or the configuration of its service failed.
- The VPN is already being used in another Windows session open on this PC, for example that of another Windows account.
- FuzeVPN only opens as a single instance: it is already starting, or its already open window cannot be displayed.
- Windows refused an operation that FuzeVPN needs for its diagnostics or for the VPN. Your Windows account’s rights or the PC’s security rules may be the cause.
Does the portable version work without installation?
Yes: extract the whole folder, then start FuzeVPN, including from a USB stick.
The interface opens with a standard Windows account. Connecting to the VPN requires administrator permission, each time you connect to the VPN.
The VPN engine and the necessary network components are also installed in Windows, in %ProgramFiles%\FuzeVPN Runtime. Your account and settings are in %LOCALAPPDATA%\FuzeVPN, outside the portable folder.
