Be sure you re-install VisiLogic "As Administrator". That means right-click on the installation file and select "Run as adminstrator". Then after installation be sure your shortcut, under the Compatibility tab, has the box "Run this program as administrator" checked.

Unless you have both

  • INSTALLED Visilogic using right click/Run as Admin, and then
  • ONCE IT IS INSTALLED AND REBOOTED you have the Compatibility tab's "Run this program as administrator" box ticked, Visilogic sometimes does strange things. 

Fully uninstall it and try again.

cheers, Aus
