The only instashield found by google is cfcs-floorcare.com/instashield/ and seems unrelated.
So please tell more, like when you exactly you get this error on your Windows Server 2012 system (or is it your Windows 8.1 PC/laptop?) and why you think the version of Internet Explorer is relevant for the problem.
Hoping someone can help me figure out what is causing this error to get rid of it finally.
Error Code: -5001 : 0x80070002
windows 8.1 / Server 2012 R2 Service Pack 0 (9600)
IE Version: 9.11.18362.0
I am unable to attach or upload the screenshot, So I have mentioned the details of an error.
