Unable to cast COM object of type ‘System_ComObject’

Asked By 30 points N/A Posted on -


I am getting this error message in Microsoft SQL server Management Studio while working with the Interface type. The error says that the operation failed because the Query Interface call on the COM component for the interface. Please explain me to solve this problem. Is the problem with the interface type or with the component? Help please.

This problem can be solved by fixing some registry issue with several DLL files.

  1. Start an elevated Command Prompt. Right-click on Command Prompt, select “Run as administrator”.
  2. Run the following command:
    regsvr32 "C:Program FilesInternet Explorerieproxy.dll"

If that doesn’t fix this issue,

  1. From the elevated Command Prompt, run the following command:
    regsvr32.exe /u actxprxy.dll
    regsvr32.exe actxprxy.dll

This will un-register and re-register “actxprxy.dll”.

If possible, install the latest update of Internet Explorer. Download Internet Explorer.

Now, your problem should have solved.
