If you are using a concurrent instance license, you need to apply two more operations:
- Call method SetMaxConcurrentInstanceCount to set the license count you purchased.
- Update the parameter MaxParallelTasks to align with the purchased quantity.
- C++
int licenseCount = YOUR-PURCHASED-LICENSE-COUNT; int errorCode = 1; char errorMsg[512]; // Set the license count you purchased SetMaxConcurrentInstanceCount(licenseCount); errorCode = CLicenseManager::InitLicense("YOUR-LICENSE-KEY", errorMsg, 512); if (errorCode != EC_OK) cout << "License initialization error: " << errorMsg << endl; CCaptureVisionRouter *cvr = new CCaptureVisionRouter; // Update parameter maxParallelTasks SimplifiedCaptureVisionSettings setting; cvr->GetSimplifiedSettings(CPresetTemplate::PT_READ_BARCODES, &setting); setting.maxParallelTasks = licenseCount; cvr->UpdateSettings(CPresetTemplate::PT_READ_BARCODES, &setting); // add further process
