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."
Install the following Microsoft update.
The "Universal C Runtime library" is normally updated by "Windows Update", but an update may have failed. Installing the update via the Microsoft help article will resolve this.
