Software

  • LabVIEW

Issue Details

  • LabVIEW installation takes significantly longer than expected (e.g., more than 1 hour).
  • Installation appears stuck during initialization or component installation.
  • Progress bar advances very slowly or pauses for extended periods.

Solution

Slow installation is typically caused by environmental factors rather than an issue with the LabVIEW installer itself. The most common contributors include security software, network conditions, installation size, and system performance.
 

1. Security Software (Firewall / Antivirus / Windows Defender)

 

Security software is one of the most common causes of slow installation. It may:

  • Block installer actions
  • Scan each file during extraction
  • Delay network communication

Recommended Actions:

  • Temporarily disable the firewall during installation.
  • Temporarily pause or disable third-party antivirus/firewall.

 

2. Windows 11 Security Features (Smart App Control)

 

On Windows 11, installation delays may occur because:

  • Each file is verified and scanned during extraction
  • Smart App Control and Defender perform additional validation checks

Recommended Actions

  • Disable Smart App Control
    • Note: Once disabled, Smart App Control cannot be re-enabled without a clean install or PC reset.

 

3. Slow Network or Download Speed

 

If installing via NI Package Manager (online):

  • Network speed directly impacts installation time

Recommended Actions

  • Test internet speed
  • Try a different or faster network
  • Close unnecessary applications
  • Use offline installer
