Install 2 versions of LabView on one pc

[Rlima]

 Hi 

 Does anyone knows if I can install   two version of LabVIEW,  currently  have  version 7

 installed with  VISION, IEEE, drivers,  I need to updrade  my software to  7.1,  I  have the

 developer suite,  but I waht really need is to install  SQL Toolkit but this is a newer version

 don't know if this will work with  version 7.  don't have any toolkits for version 7.

 I don't want to make a mistake and end with a non working computer.

Worst ting  will be to restore my computer ans start from zero with version 7.1. (don't  have

 time to do all this)

 Best Regards.

 Rlima.

I know for a fact that many people have several versions of LV installed on the same computer. 

I do know that some toolkits can only be installed once and registered to a single version at one time.

There is no problem doing that. Since LabVIEW 5.1 I think, they always install in different default directories, unless you choose to upgrade an existing installation.

However make sure to always start with the lowest version first as otherwise you can end up with a real mess. And yes some toolkits will only install once and usually default to the highest currently installed LabVIEW version as installation target. It usually works to go through the LabVIEW installation and copy the relevant directories to other LabVIEW versions though but of course they won't be deinstalled that way ever. Just checkout the release notes of each Toolkit because each Toolkit is usually compiled for a certain version and can of course only be copied to LabVIEW installations down to that version.

Special Toolkits and Drivers that will not always work between many different versions are for instance LabVIEW DSC, Vision, NI-DAQ so usually quite huge systems installing a myriad of DLLs and subparts.

Installing Toolkits for Use with Multiple Versions of LabVIEW - It is a pain but it works.  You only need to do this for the toolkits.  LabVIEW will install into its own directory.
