Hi martym,

Why Do I Get A "Missing Distribution" Error When Trying to Build an Installer from LabVIEW 8.0?

My guess is that, when you include DAQmx 8.7, there is some shared component that hasn't been updated from DAQmx 8.6. Inserting the original 8.6 install disc should fix this, but it may be that you have had a different version of 8.6 (such as 8.6.0f6) on your system than on your disc (you can check the full version number in Measurement & Automation Explorer under the software tab).
I would recommend installing the latest version of DAQmx (8.7.1)

to see if that updates the component and fixes the problem. If not, please create a log when you try to build the installer and post it here by:
1. Navigate to the C:\Program Files\National Instruments\LabVIEW 8.X directory.
2. Open up the LabVIEW.ini file and copy the "CDK.EnableLog=true" text to the bottom of the file. Enabling this feature will cause a detailed debug log to be written to your temp directory.
3. Save the changes and close the ini file.
4. Attempt to build your installer
The debug log should be located in the %temp% directory of your computer (%...% means a computer variable). To determine where this temp directory is located, follow the steps below:
1. Select Start » Run, type in "cmd" and then press OK.
2. Type "set" in the command prompt. This will return all of your computer's variable names.
3. Look for TEMP in the list of variable names. You should see something like "TEMP=C:\DOCUME~1\user\LOCALS~1\Temp".
4. Navigate to this directory using Windows Explorer. You should see a file named "Name.log" where "name" is the name of your build specification. For example, you might see "My Installer.log" if the name of your build specification is "My Installer".
