Error writing temporary file. Make sure your temp folder is valid"

. Try this method to solve the problem: press Win+S, search for Command Prompt, right-click the top result and select Run as administrator.
Type the following commands. Make sure that you press Enter after you type each command.

cd %temp%
echo test > temp.txt
del temp.txt

If no errors were printed, download MTA again from https://mtasa.com/ and try to install it.
