I will tell you a descriptive way of using Putty to access your EC2 Instance

Step 1. Download puttygen for creating a .ppk file as putty doesn't accept .pem file generated by AWS.

Step 2. Convert your .pem file to .ppk file using PuttyGen.

Load your .pem file generated by AWS. Then save the private key (.ppk) file.

Step 3. Open Putty

Add you IP.

Add user name 

Add your ppk file 

Click on Open.

Give the ip address or the host name. Then in data section give the User name for the instance for linux its generally "ec2-user".

Step 4. Click open. 

Here it is. Now you can access your EC2 instance.

The error you were getting was because of the key file. 

Either the key file was not generated or you would be using the .pem file instead of .ppk.

Hope this helps.

Hi,

There may be several reasons behind this error. One is already highlighted by @Priyaj in his answer. Apart from that also check the inbound rule in the EC2 instance. You need to allow port no. 22 in your instance as well.
