Problem: 

An Accessdata application (e.g. PRTK) will not start properly. Instead, the application throws a Windows error similar to the following:

"The program can't start because api-ms-win-crt-time=l1-1-0.dll is missing from your computer. Try reinstalling the program to fix this problem."

 

Solution: 

Install the following Microsoft update.
