Game Input MultipleXer

I Cant Install It, All It Says When I Try To Install It Is That "Windows SmartScreen Protected Your Device" And It Only Has A "Don't Run" Option And The Worst Part Is That I Even Tried To Install It After Turning Off Real-Time Protection, And It Still Said The Windows Smartscreen Thing.

Please I Want To Use My Adapter. Help.

I am not sure where the problem is. Can you post a screenshot?

You can disable Smartscreen or just set it to warn then you will have an option to continue

Windows 10 Pro

Tap on the Windows-key to display the Start menu.
Type gpedit.msc and select the result (it may be called Group Policy Editor or gpedit.msc).
Go to Computer Configuration > Administrative Templates > Windows Components > File Explorer
Double-click on the policy Configure Windows Defender SmartScreen
Set it to Disabled
Click on ok to save the change.
Note: if you want to keep SmartScreen turned on but want it to be less invasive, you may set the policy to enabled instead and the setting to "warn". The only two states you can set SmartScreen to are "warn and prevent" or "warn". The default is warn and prevent and it won't show options to bypass the warning. If you want that option, you need to switch the policy to warn instead.

Windows 10 Home

Tap on the Windows key to open the Start menu.
Type regedit.exe and select the result.
Confirm the UAC prompt.
Go to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System
Double-click on the value EnableSmartScreen
Set the value to 0 to disable SmartScreen, to 1 to give users warnings, and to 2 to require admin approval. The default is 1.
Restart the PC after you made the change.

Hope it helps
