[Closed]Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.VisualStudio.OLE.Interop.IServiceProvider'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{6D5140C1-7436-11CE-8034-00AA006009FA}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

Close:

regsvr32 "C:\Program Files\Internet Explorer\ieproxy.dll"

if you are running 64 bit windows, try this:

regsvr32 "C:\Program Files (x86)\Internet Explorer\ieproxy.dll"

The solution that worked for others:

First deregister the dll:

C:\windows\system32\regsvr32.exe" /u actxprxy.dll

Then register it again: "C:\windows\system32\regsvr32.exe" actxprxy.dll

Deleting the folder in AppData solved my problem.
1.) If you can’t see AppData, turn on Show hiddel files, folders or drives and disable Hide protected Operating System files (recommended)
2.) You can do this by in Win7 (and Vista) by opening an explorer window, hit “ALT-T” chose Folder Options then go to the view tab.
3.) Select show hidden files,folders and drives. Then click ok.
4.) Now you can see the AppData folder . Go into AppData folder select the Local folder and Delete the Microsoft_Corporation folder.
