Thanks for posting your question. If you see a pop-up window that gives you the option to investigate this internal error, make sure you choose "investigate later", and note the location that the log file is saved to.
In case we are unable to obtain the error log file, I have some questions for you. What addons or toolkits are you using in your project? What versions are they? Are you using DAQmx and if so, what version? When you create an installer for another project do you receive the same error, or is it only this specific project? Is there anyway that you could post your project and I could attempt to reproduce the error on my machine? Any information would be helpful in troubeshooting this error, thanks!
