Who likes to resurrect 6 year old posts...this guy. So over the years I've updated my LabVIEW Tray Launcher tool. It has very similar functionality as the one mentioned 6 years ago, but with some new features, and a few features that are the same but done better. Launching, killing, and restarting LabVIEW versions should work on all versions, but it is untested with 64 bit versions. It has been tested in 64 bit Windows, with 32 bit LabVIEW. Aborting VIs should work on all versions 2011 a newer. Older versions can be supported with more effort. Aborting VIs don't abort asynchronous clones. LabVIEW Run-time, or development 2011, 2012, 2013, or 2014 needs to be work. Others can be supported with more effort. By default opening VIs, and CTL files is done through this program and not LabVIEW. This allows these files to be opened in the right version. Other file types have varying level of support, but should work if they are added to the settings. If multiple versions of LabVIEW can open a file a dialog will show the available options. If only one version of LabVIEW can open the file it will open it with that version. If multiple versions of LabVIEW can open a file, but one is open already that can open it, it will open it with that version. If Shift is held when opening the file, a prompt will always be shown giving the option of what version to open it with. When opening the file VI Server is used, so unique server ports are needed between LabVIEW versions. If VIPM is configured and works, so should this. Pressing CTRL at the LabVIEW selection screen will open it in the default version of LabVIEW, or the oldest if the default isn't an option. This is all hosted on my personal site for now. It is a little large for a forum post, and the Code Repository blocks it, probably because it contains EXEs. So for now it will live on my site here.

The official advice is to use some arbitrary primitive hidden in the utilities directory (VariantFlattenExp.vi) that takes a version number . I wonder what potion they were drinking when they came up with that gem?
