i think no any solution for your question. your dll may be use any activex object that it's required to register in windows registery HKEYs. u most register your com class in windows registery. see your comm class help. We Can Do Anything, If We Want It

Hello Piyush: The original error which you are getting is a very generic error. This error may arise because of the fact that ASPNET account is not given sufficient permissions to access the resource. I would suggest you to try following steps: To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access. If this does not work then, please let us know which COM DLL are you looking to use in your application? If you open DCOMCNFG from the command prompt, opened Component Services, expanded Computers/My Computer/DCOM Config, then do you see Application (DLL which you are looking to use)? If yes, then please select the same application, right click on it and click on Properties and in the resulting dialog select Security tab. Under Security Tab, click on Launch and Activation Permissions to customize, Access Permissions to customize and configuration Permissions to customize. And in all of these three select the ASPNET account.
