Do anyone understand how i can get duplicates ??

I think it is because my webhost have the 4.0 framework. So is there anyone who knows how to get around this problem and use nopcommerce in 4.0 framework?

NopCommerce should work fine on .net 4.0...
BTW the screenshot is not visible

It seems that when you have IIS 7.5 it includes some of the elements in the machine.config so you have to adjust your web.config file. For deeper explanation look into this url: http://www.asp.net/learn/whitepapers/aspnet4/breaking-changes#0.1__Toc256770149 .

Anyways i managed to get around that by deleting the duplicates and adding this allowDefinition="MachineToApplication" to the section elements. But now i get new error in the urlrewriting config source. Here is the screenshot for that error:

According to what you told me, it happened beacuse of duplicated settings (at server level).
IIS6 is overriding with less hassles parameters setted on application level. Despite IIS 7/7.5 could do the same, it  needs special settings to do so

I didnt get it sorry. Can you clear it for me? I need to setup iis with some special settings or?

If you already configured the folder as application, try deleting the setting from web.config. It is possible that also others will throw errors.
