I don't understand why I have this problem
Please access to and choose Comprar works fine
Please select Amouage from left menu and you get the address
Now click on Comprar and you will get the Validation of viewstate MAC failed

There are several reasons for this error, such as the web application is running in a farm (multi-server environment) or worker process uses the IIS 7.0 application pool identity.

You have to generate one machineKey and write the machineKey in web.config like
<compilation debug="true" targetFramework="4.6.1"/>
<machineKey decryption="AES" decryptionKey="720B491FAE8F328CBFF487769429136AD05499388F323009D3402EA6607DE242" validation="HMACSHA256" validationKey="07719BC44522BFC74E5E7C28289DDC3BC6AE851D29AD3D88D64D50792002B5526E647716B96166494F8CC48BD35AABBF3281CA3FA1803651745AA2D8D0EA3C70"/>
