BPC 7.5 Web Administration / Set App Params asks for AntiXSSLib 1.5

Question

Hi. We have now installed BPC 7.5 in our test environment, but are facing a problem.
According to the installation guide, we have installed Microsoft AntiCross Site Scripting Library 3.0 on our app/web-servers.
But when trying to enter "Set Application Parameters" in the Web Administration tool, we get an error quite not expected:
Any ideas of why it asks for v1.5, which were used by BPC 5.1?

Hi Malin,
You are having a problem with you AntiSssLibrary.dll. Either it is not installed correctly or it is corrupted or in the wrong version.
You can take the following steps to ensure that you have a fully functional version of  the Microsoft Anti-Cross Site Scripting Library:                                                                               
1) Download the Microsoft Anti-Cross Site Scripting Library V1.5 from http://www.microsoft.com/downloads/details.aspx?FamilyId=EFB9C819-53FF-4F82-BFAF-E11625130C25&displaylang=en                                                                               
2) Uninstall the current version of Microsoft Anti-Cross Site Scripting Library and remove any AntiXssLibrary.dll file from your server;                                                                               
3) Install the version that you have downloaded from the MS website;                                                               
4) Copy the AntiXssLibrary.dll file from C:\Program Files\Microsoft Corporation\Anti-Cross Site Scripting Library V1.5\Library\.NET 1.1\   (Make sure that you're copying from the .NET 1.1 folder, not 2.0);                                                                               
5) Paste it under your \BPC\Websrvr\Web\bin folder and restart IIS.
Best regards,
Rodrigo
