Issue Details

I am using LabVIEW 2015 SP1. During the mass compile of my project, I received an Compiler Error: EventData copy, err=1. It does not say anything about possible reasons for failure. Even if I make some changes in the code, the error remains the same. 

Additional troubleshooting already is done:

  1. Created a new project and compiled it - success
  2. Compiled other projects are already done in the past- success

It seems, that only this specific project is faulty.

Solution

This issue looks like software corruption. If it is possible, please create a new project and copy the old content to it, from the faulty project. If it will not help, follow those steps (After each step try to check if it helped):

  1. Reinstall LabVIEW (If it is possible, upgrade it to a newer version)
  2. Reinstall whole NI Software
  3. Generate NI MAX report and contact National Instruments Technical Support Team
