April CU13 unexpected version

Dear All,

Our SharePoint Server 2010 server (single server) farm is at this level 14.0.6106.5002. To my understanding it is SP1 with June CU 2011.

Now we would like to upgrade the server to level April 13 CU. I have therefore followed this linkhttp://support.microsoft.com/default.aspx?scid=kb;EN-US;2775353 and request the hotfix.

The file I downloaded is 462150_intl_x64_zip.exe

Yesterday I tried to apply the CU and I got an error "unexpected version".

I believe that I have downloaded the right file to update the firm, but I'm not sure why I get the error.

Could you please help?

Thanks,

Edy
