trying to install the driver for SB322QK from here, Product Support - SB322QK | Acer United States, gives an error that the driver is not signed. Looking in to the issue further I can see there is a typo in the name of the .cat file. There is an extra space at the end of the file name before the .cat extension. I have tried manually changing the file name of the .cat file and changing the name of the .cat file inside the .inf file. In both cases that allows windows to find the .cat file but it then gives an error that the hash for the inf file cannot be found in the .cat file. I think someone at Acer must have modified the inf file to fix typos after the .cat file was generated and signed. I think the .cat file needs to be generated and signed again.

    It looks like Windows is blocking the installation because the driver isn't digitally signed. This is a security measure to ensure that only verified drivers are installed. However, there are ways to bypass this if you're sure the driver is safe..

    Try to disable driver signature Enforcement Temporarily – You can restart your computer in Advanced Startup mode and disable driver signature enforcement for the current session.
    Enable Test Signing Mode – Running bcdedit /set testsigning on in Command Prompt (as administrator) allows Windows to install unsigned drivers. Just remember to turn it off afterward with bcdedit /set testsigning off

    Try downloading it again from Acer official website SB322QK downloads

    @Sharanji I did download from the official website. Someone at acer made a mistake when signing the driver. The signed .cat file is present but there is a typo either in the name of the .cat file or in the path to the .cat file saved in the .ini file. When I try to fix either of those myself I get an error that the .ini file cannot be found in the .cat file. Somone at Acer should fix the typos and repeat the signing process. Disabling driver signing would probably work, but I am hoping someone at Acer sees this and fixes it.
