CISCO 1700 series UPDATE IOS ERROR

I got this error, but I am not sure about what do I have to do here:
(Also: FYI: I delete the old configuration to have more space, so that cannot be the problem.)
Configured I/O memory percentage was too large. Using 15 percent.
To avoid the warning, save the configuration.

The problem looks like your router doesn't have enough memory to run the image. A router has Flash which is where the image will be stored but RAM or running memory looks to be less then required by the image.

That version/feature set requires 24MB of RAM. You've only got 16MB.

Add more memory or downgrade the IOS.
