# Why am I getting the error "Please provide the correct verification code" in registration process wh

### Description

[Registration](/opstech-docs/7.223/getting-started/installation.md#registration) is one of the steps in installation. At the time of registration, user is required to provide the verification code which was sent to his/her business email address. This error may be encountered during the validation of verification code.

### Solution

Verification Code is unique for each machine and installation path. The code generated for one machine or path won't work for a different machine or path.\
For e.x, during registration process of installation, the verification code is generated for System A and later the same verification code is used on System B for validation. In this case <code class="expression">space.vars.SITENAME</code> will throw an error: "Please provide the correct verification code".

This error will also occur if for the same machine the verification code is generated for some installation path (`folder A\folder B`) and later used for installing <code class="expression">space.vars.SITENAME</code> at another path (`folder C\folder D`).

So make sure that the verification code is generated for the same machine and path where <code class="expression">space.vars.SITENAME</code> is to be installed.
