It seems like you're facing driver issues with your Pro100+ network adapter on Windows 7 RC build 7100. Let's try a few steps to troubleshoot this: 1. Windows Update: - Sometimes Windows Update can automatically download and install the necessary drivers. Make sure your system is connected to the internet and check for updates. 2. Compatibility Mode: - You can try installing the drivers in compatibility mode. - Right-click on the driver setup file and select "Properties." - Go to the "Compatibility" tab. - Check the box that says "Run this program in compatibility mode for." - Choose the operating system for which the driver is designed. - Click on "Apply" and then "OK" to save the settings, and then try running the installation again. 3. Manually Installing Drivers: - If Windows Update doesn't find the correct drivers, you can try manually installing them. - Download the latest drivers from Intel's website for your Pro100+ network adapter. - Go to Device Manager (Press Windows key + X, then select Device Manager). - Find the network adapter with the missing driver (it should have a yellow exclamation mark). - Right-click on it, select "Update Driver Software," then "Browse my computer for driver software," and browse to the location where the drivers are saved. 4. Driver Update Software: - Alternatively, you can use third-party driver update software like DriverPack Solution or Snappy Driver Installer to automatically find and install the drivers for your hardware. Try these steps out, and let me know if you encounter any issues during the process.
