How Can I Disable LogosXT and Use Logos?

Primary Software: LabVIEW Development Systems>>Professional Development System
Primary Software Version: 1.0
Primary Software Fixed Version: N/A
Secondary Software: LabVIEW Modules>>DSC Module

Problem:
I wrote a program using Logos.  Now that LogosXT (with LabVIEW 8.5) has released I have noticed that the shared variable behavior has changed. I need a way to turn off LogosXT to keep my original shared variable behavior.  How do I turn off LogosXT?

Solution:
The method for turning off LogosXT is different depending on which OS your program is running.

Windows
To disable LogosXT on Windows, you must add an entry to the Windows registry.  Here is the key to add:
HKEY_LOCAL_MACHINE\SOFTWARE\National Instruments\LogosXT\DisablePSPXT

Set this key to a DWORD value of 1.  Upon rebooting your system, the key will take effect and you will be running Logos instead of the new LogosXT.

Note:  National Instruments strongly suggests making a backup of the registry before editing.  Take extreme caution when editing the registry, as you can affect the integrity of the operating system.

Real-Time
When disabling LogosXT on a Real-Time operating system, you must add an entry to the ni-rt.ini file on the target.  Follow these steps:

  1. FTP to the RT system by opening an Internet Explorer window and typing
    ftp://IP-ADDRESS 
    where IP-ADDRESS is the actual IP of your RT system.
  2. Locate the file named ni-rt.ini and copy this file to your system.
  3. Open the file with a text editor and add this section:
    [logos]
    PSP.DisableLogosXT=1
  4. Save this file and FTP it back over to the RT target.
  5. Reboot the target.  It will boot up running Logos.
