800401f3 in ASP using IIS

I have a big problem here.

This is my configuration

Windows 7 Professional with Service Pack 1

IIS 7.5

Crystal Reports XI R4 this is the specific version 11.5.10.1263.

When i try to see the reports in Internet Explorer, i receive this error:

<font face="Arial" size=2>

<p>Objeto de servidor</font> <font face="Arial" size=2>erro 'ASP 0177 : 800401f3'</font>

<p>

<font face="Arial" size=2>Falha em Server.CreateObject</font>

<p>

<font face="Arial" size=2>/ServidorRelatorio/CrystalReport.asp</font><font face="Arial" size=2>, linha 14</font>

<p>

<font face="Arial" size=2>800401f3

</font>

What is happening?
