Please provide more information - relevant settings in web.config, authentication method etc.

My web.config file looks something like this.

<configuration>
<system.web>
<httpModules>
<add name="LogModule" type="LogModule"></add>
</httpModules>
<compilation debug="true"/>
<authentication mode="Windows" />
<identity impersonate="true"/>
<trust level="Full"/>
<trace traceMode="SortByCategory" enabled="true" localOnly="true" pageOutput="false" requestLimit="10"/>
</system.web>
</configuration>

By Default

ASPNET or IUSR account which is used to execute ASP.net websites has only guset permissions. you must sent executeable permission for your website to some Administrator Level account. in that case you will be able to access registry. otherwise it will throw an exception
