LabVIEW Developers Feature Brainstorming
In some documentation it says that you can install more than one RunTime engine for older versions of LabView eg I have a dll which wasmade using v7.1 and I now have 8.2.1. When i call it from visual basicit complains that I need the older run time engine. Ok so I downloadit but when I try to install it it won't let me since I already have alater (8.2) run-time engine installed!!!Any thoughts?Hardy
The only way I know of to have multiple versions of the RTE installed is to install them in order. Unfortunately that means you have to uninstall the newer one(s). I'd sure like for someone to chime in with an anternative though. Matt
I'm not sure about that but it might help installing an application (including run-time engine) built in 7.1. Daniel
Hello all,A few customers have run across this error specifically with the LabVIEW 8.2 Run-Time Engine. However at this point we have been unable to reliably reproduce it. We've tried installing the LabVIEW 8.2 Run-Time Engine on a clean machine followed by installing the LabVIEW 7.1 Run-Time Engine and it seemed to install fine. We've also tried with LabVIEW 8.2.1 and 7.1.1. If you have an idea regarding how to reproduce this error please post it here. Some customers have found that in the past installing an application that includes the LabVIEW 7.1 Run-Time Engine as mentioned above by Dan has solved the problem. The other alternative is to uninstall the LabVIEW 8.2 Run-Time Engine and install the previous Run-Time Engines as Matt suggested above. Thank you all for your contributions!Regards,Erik J.

I just tried to install the LVRTE 7.0 onto my development machine (7.1.1 and 8.2.1 installed already)and got the attached error. My experience has been that any RTE install will abort if there is alreadya newer version installed. Were there changes to 8.2.1 to allow an earlier version to install? Thanks. Matt

Thank you for your post Matt. It appears that if a later version of the development environment is already installed then a run-time engine of an earlier version will abort. However it seems that if the machine has only run-time engines on it you should be able to successfully install previous versions. LabVIEW 8.2.1 will still show this behavior. Unfortunately at this time the best solution is to uninstall the newer versions of the LabVIEW Run-Time Engine. However we are looking into fixing this problem in future versions of LabVIEW. Thanks again!Regards,Erik J.
