When attempting to run K2 for Visual Studio with the "Run as Administrator" option as per:

https://www.k2.com/onlinehelp/k2connect/userguide/current/default.htm#How_to_Start_a_new_Project.html?Highlight="Run As Administrator"

A User Account Control prompt is displayed with the "Do you want to allow the following program to make changes to this computer?" and asks for an Administrator account and password.
 

Diagnoses

The prompt screen that you are seeing is Windows' User Account Control (UAC), that will usually prompt for standard account and even local administrator account. This is a Windows setting that can be changed/disabled as you deem applicable. Please see the documentation below:

"User Account Control (UAC) is a feature in Windows that can help you stay in control of your computer by informing you when a program makes a change that requires administrator-level permission. UAC works by adjusting the permission level of your user account. If you’re doing tasks that can be done as a standard user, such as reading e‑mail, listening to music, or creating documents, you have the permissions of a standard user—even if you’re logged on as an administrator."
