A little problem with uploading sketches

Hello, I am very new to the whole micro-controller thing. Having just had my Arduino arrive, I tried to upload a new sketch and had a problem. I thought I would ask for help here among people who can help me. The problem is that, after verification (which is fine if a little slow) I try to upload it to the Arduino using USB. This however seems to be a problem as it says that it cannot find 'COM1'. The exact message is "Serial port 'COM1' not found. Did you select the right one from the Tools > Serial Port menu?". I then try to change it and find that this menu is greyed out meaning, presumably, that there are no other options.
I assume that this is an issue with drivers but cannot find the right one after being bounced around by links on other Fora.

Any help would be greatly appreciated

The following procedure will help you install the drivers for your Arduino board:

Go to Device Manager
Right click the unknown device in Device Manager \ Other Devices
Select Update Driver Software
Select Browse my computer for software
Click Browse button
Select the Drivers folder under the location of your Arduino software installation
Click OK
Click Next

Thanks for that - still a little confused
Do I need to add the driver folder or is it a specific driver in that folder - it sounds like the whole thing

Thanks

Select the Drivers folder under the location of your Arduino software installation

You are selecting the folder and not anything inside of it.

Thank you very much to all who replied - it's installing the driver software now lets see if it works...

It does - it is fading well

Thanks to all that helped - I didn't realise that the whole driver folder needed to be added!
