The following applies to the IFC200, IFC202, IFC300, IFC400, and RFC1000.

The standard method of installing the USB drivers is to run the "PreInstaller.exe" USB driver installation utility before plugging in the IFC.  Locate the PreInstaller on the MadgeTech installation flash drive, or download the USB driver zip from the software download page.  If the PreInstaller will not run, or crashes without installing, install the USB drivers manually.

Plug in the IFC, and locate it in Device Manager.  To open Device Manager, go to the Start Menu, right click on Computer (or This PC in Windows 10), and select Manage. In the left column of the Computer Management window, select Device Manager.

After selecting Device Manager in the left column, a list of devices will appear in the right column. If the USB drivers for the data logger interface have not been installed properly, it will typically appear as an item in Other Devices with an exclamation point or a question mark. This is usually called Unknown Device, USB Docking Station, or something similar.  Right click on this item and click properties. In the following window, click the driver tab and select Update Driver. The next steps will vary based on the version of windows.

Windows 7 and 10:
Click Browse my computer for driver software. Click Let me pick from a list of device drivers on my computer. Click the Have Disk button (if this is not an option, click All Devices, and then next. This should advance to the screen with the Have Disk option). Click the Browse button to open a Locate File window.  Browse to the MadgeTech installation media (software flash drive or software CD) and open the USB folder.  Alternatively, if installing drivers downloaded from the software download page, navigate to the folder extracted from the USB Drivers zip file.  Select the mtiUSBXp.inf file and click Open and then click OK.  Select data logger Interface under Model, and then Next. The data logger Interface driver to your IFC. Click Finish.

Windows XP:
The Hardware Update Wizard will prompt to connect to Windows Update to search for the software. Select No, not this time and click Next. Select Install from a list or specific location [Advanced] and click Next. Select Don’t search. I will choose the driver to install and Next. On the next screen pick Have Disk (if this is not an option, click All Devices, and then next. This should advance to the screen with the Have Disk option) button to open a Locate File window.  Browse to the MadgeTech installation media (software flash drive or software CD) and open the USB folder.  Alternatively, if installing drivers downloaded from the software download page, navigate to the folder extracted from the USB Drivers zip file.  Select the mtiUSBXp.inf file and click Open and then click OK.  Select data logger Interface under Model, and then Next. The data logger Interface driver to your IFC. Click Finish.

At this point the driver should be correctly installed.  A software or computer restart may also be required before the data logger will be recognized.
