I installed the Business Portal 6.0 with Benefit Self Service Module. Everything is fine, Employee List is coming out fine, Employee Information and other data is okay. But on accessing the Addition Benefit Information link on Employee\Benefit Page, it shows the errors as pasted below.

Apparently in all the three web parts it is not able to find the Benefit Self Service at http://servername:48620/Dynamics/BSSService/Benefit_Self_Service.

While the Dynamics service is showing fine.

I was able to find literally nothing on this issue but going through the documentation, I found a document named BPHRPSuiteInstallation.pdf. It says what is pasted below.
Initial Installation
To configure BSS Web Services:
This procedure configures BSS Web Services for the Human Resources and Payroll Suite for Business Portal. It only needs to be performed if BSS has been installed. It requires that Microsoft Dynamics GP Web Services has previously been installed.
1.
From the server that is running GP Web Services, access the BSSWebServiceConfig.exe in the directory where Microsoft Dynamics GP Web Services was installed. By default, this is \Program Files\GPWebService.
2.
Double-click BSSWebServiceConfig.exe and follow the on-screen instructions.
For 1, I was able to find the GPWebService folder under Program Files/Microsoft Dynamics/GPWebService, but I couldn't find any file named BSSWebServiceConfig.exe. The only executable file related to BSS found was Integrity.Data.BSS.GPWebService.Security running which it closes unexpectedly.

I guess the service did not install and I do not have any installation file to do it. Any help in this would be appreciated.
