Everything seems to run fine until I try to obtain either a wx report or clearance and then I get the following Runtime 75 errorRadar Contact.fsuipc.rcv4 code Not sure if the code is missing or corrupted. Anyone have any ideas how to correct this error?

http://forum.avsim.net/topic/100174-error-75-radar-contact-and-kapersky-and-norton/ It would be a good idea to create a shortcut to RC and FS. In each right click and set the properties to run as admin. This is an application privilege, not a user privilege, that allows an application to go where it needs to via files or the windows message internal processes. In addition make sure RC is selected in your security applications to be safe and allowed to pass as noted in that pinned thread.
