I am having issues with Visual Studio and deploying to IIS on Win2003. I am able to create and run my web service fine locally on WinXP but when I try to deploy and run it on the server I get the error message: System.InvalidCastException: Unable to cast COM object of type 'REDotNET.REAPIClass' to interface type 'REDotNET._REAPI'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{13FCEC5E-4B9B-11D4-80B5-00B0D0119B1C}' failed due to the following error: Error loading type library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY)). This happens when I call the REAPI.init. I am able to create the REAPI objet itself but not then call init. Does any one have an idea what this means or what I can do to solve it. Thanks David Zeidman Development http://www.zeidman.info

My guess would be its a permissions issue. Check the permissions that KB (BB121222) refers to. If that doesn't work you may have to use FileMon or RegMon from www.sysinternals.com . I've had to do this a couple times to get all the permissions right. The registry permissions tend to be flakey. Joel

Specifically when you are applying the Read and Execute permissions to the folders specified make sure you apply it to the folder and its child objects. Specifically: locate the folder in windows explorer Right Click and Select Properties ! Security Select Add and enter ASPNET Select OK and then Select Advanced on the properties dialog box Tick the check box “Replace permissions on all child objects …. Select Apply …
