On one of my user's computers, they get the following error when they run my code:

Main Script Name : C:UsersxxDownloadsFirmware_v270_WinEBBUpgraderGUI_v270.exe
Error code 30
Line number 26

This occurs on the following line (line 26)
Global ComputerName As String Value OS_GetComputerName

This program has run fine on thousands of different computers. Any idea what "Error code 30" is and what could cause OS_GetComputerName to fail this way?

Thanks much-
