Why does this occur "NI_Variable_RT.lvlib : GlobalVar_RT_MangleName.vi has unsaved changes?"

[Shan21]

I am trying to deploy a VI to the RT target and I get this message.

"NI_Variable_RT.lvlib : GlobalVar_RT_MangleName.vi has unsaved changes"

I am only allowed to deploy the VI if I save these changes. What are these changes referring to?

Has the link between the variables on the Host PC and RT target broken due to which this message occurs?

Hi Shan21,

Do you not get an option to view the unsaved changes? If you want to find out the changes that have taken place in a VI, here is a description. If you navigate and open the VI and then go File->VI Properties. Under the General tab there is a button marked List unsaved changes. This will show you the changes that have taken place. 

If you have made no changes that you are aware of to this VI, it maybe that you are converting it from a previous version to the most current version.

Thanks,

Well, I saw the changes which were listed but I had not made any to the program previously.

Actually, I have 2 different applications but I have to use the same RT target. When I deploy the first application VI to the RT target, it works fine. But it is only when I am deploying the second application VI to it that I get this message.

Is it something to do with this or is it only because the program versions are different?

Hi Shan21,

If you go to the list of changes, what changes does it list? Did you develop both of these applications on the same PC and at the same time? I wouldn't have thought it would have been due to putting on a different program. I suspect its probably due to a version update on one of the subVIs you are using. 

Thanks,
