Enabling NtfsDisable8dot3NameCreation Registry Entry

When using CivilGEO’s License Server Configuration Utility software on a computer system that has been upgraded from Windows 7 to Windows 10, the software sometimes fails to run. This issue occurs due to Window’s default mechanism of shortening the user’s temp folder if the username is greater than 8 bit.

This issue can be easily corrected by enabling the NtfsDisable8dot3NameCreation registry value.

Note that the NtfsDisable8dot3NameCreation registry value is enabled by default on Windows 10.
