You may get this type of error to install that driver in your computer for your operating system problem. If those driver installation requirements do not meet with your operating system, then you may show this type of error on your screen.

There showing that the driver does not meet with your current windows installer package. You can download and install individually actual windows installer from http://www.microsoft.com/en-us/download/details.aspx?id=8483 for your computer. After install that windows install reboot your computer to configure correctly. Then try to install that driver software again. If you fail again to install that with same error, you should change your windows XP service pack 2 to service pack 3.

WiDi Installer Driver Update Error 1721


Since you are using a Toshiba laptop, you should visit the Toshiba Support Page to download the appropriate driver for your WiDi-supported device. On the page, enter your laptop’s model number or serial number to access the software designated for your machine. You can also download an Intel WiDi driver from Downloads for Intel Wireless Display.

The latest versions available support Windows 7, Windows 8, Windows 8.1, and Windows 10. On the other hand, if the latest version no longer supports your device, try this. Download “WiDi setup.exe” from Intel Wireless Display Software for Windows. When I checked the download page, it seems version is no longer available. So, I guess, you should download the closest version to your device.

Once downloaded, restart your computer. Open Windows Explorer and navigate to the WiDi installation folder. For WiDi 2.0.x, it should be located at “C:Program FilesIntel CorporationIntel Wireless Display” for 32-bit and “C:Program Files (x86)Intel CorporationIntel Wireless Display” for 64-bit. For WiDi 2.1.x, it should be at “C:Program FilesIntel CorporationIntel WiDi” for 32-bit and “C:Program Files (x86)Intel CorporationIntel WiDi” for 64-bit. Look for “WiDiApp.exe” and rename it to “WiDiApp_old.exe”.

Run the setup file you downloaded. Note that renaming WiDiApp.exe will trigger a “cleanup” operation on the installer. This should fix the problem.
