To use the Intel® Driver Update Utility it is necessary to download it first and then installing it.
If the problem happened when downloading the file this means that the tool was not even installed so whatever that happened was caused by something running in the background or a Windows failure.
Based on the description you provide it looks like the graphics driver of your computer got corrupted and it will be a good opportunity to reinstall it.
If your computer is a custom build using an Intel® Desktop Board, please let me know Windows version you are using, the model number of the motherboard, and the model number of the processor so I can address you to the proper source to download the latest graphics driver.
If your computer is a branded one (Dell, Hewlett-Packard, Lenovo, etc) I recommend you to visit the manufacturer’s web side using the model number of it and search for the most recent graphics drivers.
