I am on Windows 7.

I am trying to install the Cypress USB driver by following the instructions found here:


I successfully downloaded CypressDriverInstaller_1.exe

However when I install it, it goes through most of the installation sequence and fails with this error:

“System Failed Copying files to Windows Temporary Directory. Unable to proceed…”


I tried the following and I always get the same results:

- Running CypressDriverInstaller_1.exe  as administrator
- Installing to a different directory
- Rebooting in safe mode with networking enabled.
- Installing by first extracting the files on another computer and then right-clicking “install”. I get “The INF file you selected does not support this method of installation.

My guess is there is something in the file system preventing it from installing properly. What could it be?

I tested that installer and it was working fine. It must be a PC specific issue.

You can download  the sys and inf files (driver files) from the link below:

You can manually bind these drivers to your device using the device manager,
