License Validates But Still Get Integrity Check Failed

CS cart v4.1.4, Windows Server 2016, running PHP 5.6 with no errors. Have valid licensed and validates but still get the: Warning Installation integrity check failed. Your store will switch to Free mode within 2 days.

when reload /app/Tygh from install files it goes away but so does add-ons.

Checked permission to design, var and images, all correct.

Any idea on avoiding the 2 days free mode change.
