Hi,

If I press the remove key in windows add/remove sofware, the installer says that some pieces remains not linked to a product, and if i say I want to uninstall them, I have the error 1612 for each of them. How can I remove these old things? there are
NI-PAL 1.5.5f0 Engine
NI-RPC 2.2.1f0 Engine
NI-RPC 2.2.1f0 Engine for LVRT
NI IVI Engine 1.83

I have run across this issue before and it seems the only way to get this to work is use a utility called MSI Blast. Open the zip file below, read the instructions and it will remove all NI software from your machine. Let me know if you have any trouble.

Hi and thanks for your answer,

I did the think manually cleaning the registry and National instrument dir + common files. And finally removing from Windows installation databes with the tool you proposed. But this tool is only cleaning windows installation database and unfortunately not cleaning the leftover of the application

In case it helps, here are some step-by-step instructions for how to use the MSI blast utility in conjunction with unistalling software on systems that require a clean re-installation...I hope this helps!!

thanks, I will try that if I'm still in trouble due to that. I also wonder if the issue is due to unclean reinstall or something else!
