Run Time Engine

[BTF]

Can different version of Labview Run Time Engine , example Version 6 and Version 7 exist together in one system?

What to do if there are applications build in Labview 6 and Labview 7 separately and need to be run in same system?

Please advice. Thanks !

Yes, you can install all runtime engine version at the same time on the same computer. Works just fine.

Some of my computers have 5.1, 6.0, 6.1, 7.0, and 7.1 runtime installed.

Dear Altenbach,

Thanks for your valuable info.

For Labview applications build with different version of Labview, when I run them in a system with different version of Run Time Engine installed, is it that the application will look for the correct version of Run Time Engine?

Can I run VIs that are saved in development dll in a system that only have Labview Run Time Engine installed?

Please advice. Thanks !

Everything is automatic and transparent. It will always choose the correct version of the runtime engine and you can even run different versions at the same time. It will only complain if the correct runtime version is not installed. 🙂

Sorry, I don't know what a development dll is. Could you clarify what you mean?

Dear Altenbach,

Sorry for my unclear statement. The development llb that I mean is the VI library that I created when I choose " Save with Options -> Development Distribution ".

I save VIs into this library (without removing diagram and not password protected). Am I able to run the VI in a system that only have LabView Run Time Engine installed (correct version) and not full LabView development software.

Looking forward to your reply again ... 😉 ... Thanks !

An llb is different that "applications build" or "dll". If your last post is now correct and you really only have an llb, then no, it will not run with just the run-time engine. There is a way to create an executabe that will load a VI in an llb. If you have the app builder though, it's simpler to just create an exe. What exactly do you have and what are you trying to accomplish?

Dear Mr Knutson,

In my case, there is already an exe that call and execute vi specified by user.

This exe is build by another party. I'm uncertain whether vi I saved in a llb file can be used or in this case or not. Or I need to save all vi into dll?

Kindly advice. Thanks !

So you already have a application that can load and run a VI? Then in that case, the application should be able to load and run a VI that is saved to the same version as the exe. For example, your loader app cannot load and run a VI saved in version 7.1 if the exe is a version 6.1 application.

Yes, you can run a VI that is saved in a .llb file. These are just collections of VIs. For example: If you want to run "sub.vi" that is saved in a .llb called "myVIs.llb", then you would have to call it as "myVIs.llb\sub.vi".

We have a number of applications where we distribute sub-systems in this way. To keep the customer from looking in them, all VIs in the .llb are password protected.

I have LabView 7.1 installed. When I tried to install 7.0 run time engine, it would not allow me to do so. the message shows that a exsiting another version of this product, install can not complete. It also show me how to remove the existing version. Do I have to remove 7.1 in order to install 7.0 run time engine?
