My executable compiled with Real Time Engine 5.1.1 in App Builder gives error when trying to run in App Builder with RTE 6.1

[westyoungman]

Hello.  I built an executable using App Builder in LV 5.1.1 and now, years later, I am trying to run it in LV 6.1 but I get an error stating a requirement for Run Time Engine version 5.1.1.  To be able to run this, must I install the older version of Run Time Engine?  If so, where can I find the older version?  Do I have to install the older version of LabVIEW to get the RTE?  Will having both versions on my pc be a problem?

I assume that once I am able to run the exe, that I will be able to recompile with the newer version of the RTE using App Builder.  Is this correct?

I have been away from LabVIEW for several years and am a bit rusty on these details that I once knew.  Any help is appreciated.

The version of the run-time engine must match the version of LabVIEW that was used to create the executable. You can get any version of the run-time engine you want here. The only way to create a version 6.1 exe is to re-build it from the source code with diagrams. An exe has no block diagram so it cannot be converted to a newer version.

Dennis, thanks for your prompt and simple answer.  Problem solved.  I can probably locate the source code for diagrams so I can recompile with newer version of RTE.
