 +====== Troubleshooting Lab Windows issues ======
 +===== Receiving a Change Compatibility Mode Registry Error When Launching LabWindows/​CVI =====
 +  *Primary Software: LabWindows/​CVI Development Systems>>​Full Development System
 +  *Primary Software Version: 7.1, 8.0.1
 +  *Primary Software Fixed Version: N/A
 +  *Secondary Software: LabWindows/​CVI Development Systems>>​Base Package

 +==== Problem: ====
 +When running LabWindows/​CVI for the first time after installation or when setting the compiler compatibility mode, LabWindows/​CVI reports an error indicating that it is unable to modify registry keys. The error states:
 +"This utility could not open registry entries for the given CVI version."​
 +Why am I getting this error?
 +==== Solution: ====
 +The first time LabWindows/​CVI is run after installation,​ a dialog will appear (see attached screenshot "​Compatibility Mode.jpg"​) indicating the compiler compatibility mode is being set. This action requires administrator privileges (not user or power user privileges) since registry keys are being modified outside of an installation.
 +To resolve this problem, either log in as an administrator or ensure that your user account has write access to the following parent trees in the system registry:
 +    HKEY_CURRENT_USER\Software\National Instruments
 +    HKEY_LOCAL_MACHINE\Software\National Instruments
 +If above does not help, change the permissions on following tree for Users to Full Control
 +    HKEY_LOCAL_MACHINE\SOFTWARE\National Instruments\CVI\7.1
