%hs is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0x

This issue can be solved, though it does reduce the computer's resistance to malware and other memory misuse. To make the Spiro driver work again in this scenario, you will need to turn off Memory Integrity protection.

1. Open Windows Security from the Start Menu

2. Click on Device Security, and then click on Core isolation details

3. Turn off the toggle for Memory integrity

4. Restart your computer to apply the changes
