Hi Yeshwant_Birader,
This type of lag when trying to launch NI programs whose licenses are provided by a license server is typically due to connectivity problems with the license server. To confirm this, open NI license Manager. Depending on your version, you'll either want to go to "File >> Options" or select the "Network Licenses Tab". Then, either delete the server string from the box or uncheck the checkbox for "Use Volume License Servers". You can find more details here. NOTE: If you are using the version that doesn't have the checkbox, forcing you to delete your server string, be sure to save back a copy of that string.
Once you've configured license manager to ignore the server, try to launch your software. If the lag is gone, you've confirmed the lag is due to network communication with the volume license server.
For license server issues, you'll also want to reach out to your license server administrator (if it's not you) to confirm the server is up and you are granted proper permissions as well as perform any server-side debugging.
Regards,
