Error: “Object reference not set to an instance of an object”

Error: “Object reference not set to an instance of an object”

Hi Cynthia,

what software? Smart card? check your certificate authority and try to verify if the certificate template available is valid to be issued by a CA.  It is located under Template display name header on the properties page for the profile template. But if  it is about ADO and ADO MD, accessing data using ADO interop on an AP. net page, it may cause error in service base application or in multithreaded applications and sometimes migration is the issue. 

The object that the error is  telling  us base on these two type, it could be a value type or reference type. The value type  has already a memory directed to it, but the  reference type needs variable. They are pointers to memory unlike the value type that initialized when created, and it does not need a new operator for them.  The Value type can be nothing if there is no memory address, That's why you need to assigned anything to variables, or created an instance of the value assigned to variables.

Error: “Object reference not set to an instance of an object”

I’ve seen that error couple of times on my computer also right after installing an application when I run it. It happens to me most of the time because I missed installing a component or I have an unsupported version of the component installed on my computer. Most of the time, the component I missed installing is Microsoft .NET Framework.

It only happens to me when I don’t check the system requirements which I already listed on a file stored on the installer’s folder on my hard drive. In your case, since you did not mention what application it is, you need to check again the program’s specifications and you need to meet those requirements.

If the application you’ve installed requires Microsoft .NET Framework, check what version is required and install that version or maybe higher. It is also best if your operating system is running on the latest Service Pack. If you are using Microsoft Windows XP, download and update to Windows XP Service Pack 3. This is the latest and last Service Pack update for Microsoft Windows XP.

If you are using Microsoft Windows Vista, download and update your operating system to Windows Vista Service Pack 2. This is the latest and last Service Pack update for Microsoft Windows Vista. If you are using Microsoft Windows 7, download and update your operating system to Windows 7 Service Pack 1. This is the latest and only Service Pack update for Microsoft Windows 7.

If you are using Microsoft Windows 8, you should update your operating system to Windows 8.1.
