Here to help, @NOITAX.
To provide you with the most efficient response, I'd like to gain a little insight into what exactly you're experiencing. You mentioned downloading something. What exactly were you trying to download (was it a QuickBooks installer)? Once I know this information, I'll be able to provide you with the best response.
In the meantime, I recommend restarting your computer/server. This will clear out the RAM and application processes and allow you to continue using your system.
Please know I'm always available here to lend a helping hand. I look forward to hearing from you again!
