Siebel 220.127.116.11 is supported with IIS 7.5. There should not be an issue with Win7 as well.
By default, IIS 7.5 will use 64-bit compatibility, which is not supported by Siebel applications. Therefore, the application throws HTTP Error 500.0 Internal Server Error..
Confirm that 32-bit mode is enabled on IIS 7.5:
- Select Application Pools and under Actions selected Set Application Pool Defaults.
- "Enable 32-Bit Applications" should be set to "True": Changing the parameter value to "True" allowes DLLs run in 32-bit mode.
Also please check the below module are checked and Installed in the IIS web server
1. On the taskbar, click Start, point to Administrative Tools, and then click Server Manager.
2. In the Server Manager hierarchy pane, expand Roles, and then click Web Server (IIS).
3. In the Web Server (IIS) pane, scroll to the Role Services section, and then click Add Role Services.
4. On the Select Role Services page of the Add Role Services, make sure that CGI or ISAPI Extensions are checked.
5. If they are not installed, select these modules and install the same using the add role services wizard and make sure that the application is accessible.
Setting the Enable 32-Bit Applications=true for Application Pool is still necessary if Native IIS7 is being used.

Thanks & Regards,
Thanks for the response written in so detail. I was busy with some other project delivery and could not try today the option mentioned by you.
I have done all this set up in a virtual machine. I am using Oracle virtual box. The image is using 32 bit windows 7 OS.
I checked for the option in IIS 7.5 that is installed here, but in the Set Application Pool Defaults, I could not find the option "Enable 32-Bit Applications" at all !!
I googled to see if there are other ways of setting this option , but I could not find anything on the web.
I don't know how to go about this.....any idea what could be wrong.
Thanks and Regards,
Please follow below navigation steps:
IIS Manager > Application Pools > DefaultAppPool > from right pane, select 'Advanced settings..' > In pop-up window
'Enable 32-Bit Application'= True
Thanks & Regards,
I have the same issue than Deepa, but my problem is that i'm using Apache instead IIS. So, do you know how i can force the compatibility with 32-bits without install Apache 32 bits?
