I downloaded Arduino software but it doesn't show up under the Device Manager.

Development Tools IDE 1.x

I have an XPS M1530 with Windows 10. I followed a tutorial on what to do when getting an error message when trying to use a sketch. It took me to System Security and finally the Device Manager where the Arduino Uno download should have been; it wasn't there. Someone suggested my system may not support the download. Need suggestions, thanks.

My mistake, not control panel.....doesn't show up in device manager.

I had a similar issue as well. I tried everything but this is the one that worked for me. Make sure your Arduino Uno is plugged in before doing these steps.

Steps without having to follow the link.

Follow the steps:
a) Type cmd on the Start screen and right click on Command Prompt. Select Run as administrator.
b) Type “set devmgr_show_nonpresent_devices=1″ without the quotes. Hit Enter.
c) Type “start devmgmt.msc” without quotes and hit Enter.
d) Seelct “Show hidden devices” under View menu.

Now if you expand the section on COM ports, all the COM ports that have ever been created will be displayed, the non present ones being in grey.

Now that the device is listed in the Ports (COMS & LPT). Launch the IDE, it will now show Tools->Ports (select The Port that your device showed in device manager).

if it is a clone board you may need additional drivers such as these

Also avoid USB 3.0 ports as they are known to cause some issues with Arduino boards.
