Step-by-Step Xentry PassThru 06.2021 Installation
The installation process for Xentry PassThru 06.2021 is straightforward if you follow these steps carefully. Before you begin, ensure your system meets the following prerequisites:
- Operating System: Windows 10 64-bit is MANDATORY. This version of Xentry is designed to work exclusively on this operating system.
- Disk Space: You will need approximately 40GB of free space on your C: drive for the base installation. However, it is highly recommended to have at least 80GB of free space to accommodate add-ons and future updates.
- J2534 Device: Ensure you have a J2534 compatible device like OpenPort 2.0 ready for use with Xentry after installation.
Now, proceed with the installation steps:
- Disable Secure Boot: Access your computer’s BIOS settings and disable “Secure Boot”. The method to do this varies depending on your motherboard manufacturer, but it usually involves pressing DEL, F2, F12, or ESC during startup. Consult your motherboard manual for specific instructions.
- Disable Antivirus and Internet: Temporarily disable your antivirus software and disconnect from the internet. This is crucial to prevent interference during the installation and activation process.
- Locate Installation Files: Navigate to the location where you extracted the downloaded archive files.
- Run the Installer: Locate and run the Xentry PassThru installer from the extracted files.
- Installation Settings: During the installation process, you will be prompted to choose installation options. Select “USA Client” and “Without Retail storage“. These settings are essential for the proper functioning of this particular Xentry PassThru version.
- Wait for Installation: The installation process can take a significant amount of time, typically a couple of hours. The duration depends on your computer’s performance. Allow the installation to complete without interruption.
- Restart Your Computer: Once the installation is finished, restart your computer to finalize the setup.
Activating Xentry PassThru 06.2021
After installation, Xentry PassThru needs to be activated. Follow these steps precisely for successful activation:
-
Disable Antivirus (Again): Ensure your antivirus software remains disabled during the activation process.
-
Registry Key Loader: Navigate to the “files for activation” (usually included in the download or provided separately). Run the file named “old key loader 64bit.reg“. This will add necessary information to your Windows Registry.
-
XentryAPI.dll Replacement: Copy the file “XentryAPI.dll” from the activation files to the directory C:WindowsSysWOW64.
-
Advanced Keygen Activation:
- Run “ConfigAssist” from your desktop shortcuts.
- Then, run “Advanced Keygen” (also from desktop shortcuts or activation files).
- In Advanced Keygen, click the “Try” button.
- You might see a password prompt. Ignore it and click “OK“.
- You will likely encounter one or two warning windows. Ignore these warnings and click “OK” on each.
- The Xentry Keygen activation window will then open.
- In the Keygen window:
- For “Date Start“, choose any date in the past (not the current date).
- For “Date End“, set a date in the future, for example, one year from now.
- In the “HWID” field, enter the “Hardware ID” value from ConfigAssist.
- In the “APPID” field, enter the “ID приложения” value from ConfigAssist.
- In the “Lic Num” field, enter any digit.
- Click the “Generate” button.
- Copy the generated key.
- In ConfigAssist, click the “Вручную” (Manually) button in the center.
- Paste the generated key into ConfigAssist.
-
Troubleshooting: If you encounter a key error in ConfigAssist, double-check that you have disabled Secure Boot in your BIOS settings.
-
If the activation is successful, ConfigAssist will show a confirmation similar to this:
- Important Note: The “Подключение к серверам” (Server Connection) status might not always be active. Ignore this status. Online connectivity is not required for the functionality of this Xentry PassThru version, and this status does not affect the program’s operation.
-
License File Modification:
- Navigate to the hidden folder C:ProgramDataLicDir. You may need to enable “Show hidden files and folders” in Windows File Explorer to see this directory.
- Locate the license file named “lic_key_2.dat” that was just generated during activation.
- Copy this file into the same C:ProgramDataLicDir folder.
- Rename the copied file, changing its extension from “.dat” to “.x4711”. The new file name should be “lic_key_2.x4711“.
- In the C:ProgramDataLicDir folder, you should now have two files:
- lic_key_2.dat (the original generated file)
- lic_key_2.x4711 (the renamed copy)
- For both files (“lic_key_2.dat” and “lic_key_2.x4711”), right-click on each, select “Properties”, and check the “Read-only” attribute box. Click “Apply” and “OK”. This step is crucial to prevent the license from being invalidated if your computer connects to the internet.
