Error 267 at System Exec VI When Using DigitalPatternCompiler

Issue Details

When calling DigitalPatternCompiler through the System Exec.vi in LabVIEW to convert or compile patterns (e.g., from PXI-6551 HSDIO to PXIe-6570 Digital Pattern), the following error occurs:

Error code: 267 (0x0000010B) 
Error 267 occurred at System Exec.vi. Command was...

Solution

Root Causes

1. Malformed Command String: Inconsistent or extra double-quotes in the command string. For example, ending a path with "" without a matching opening quote causes Windows to treat the argument as malformed.
2. Invalid Working Directory: The "working directory" input to System Exec.vi is not a valid path to an existing directory or contains non-printable characters like extra spaces or carriage returns.
3. Unresolved Executable: The DigitalPatternCompiler is not in the system PATH, and the VI is calling it without a full absolute path.
4. Missing Output Directory: Some tools fail if the specified output directory does not already exist on the disk.

Resolution Steps

1. Ensure all paths are properly wrapped in a single set of double quotes and check for trailing spaces or extra quotes at the end of the string.
2. Use Absolute Paths: Instead of relying on the system PATH, provide the full absolute path to the compiler (e.g., cmd /c "C:\Path\To\DigitalPatternCompiler.exe").
3. Ensure the directory passed to the working directory terminal exists.
4. Add logic to your VI to verify and create the output directory (e.g., ...\Compiled Patterns) before calling the compiler.
