When replacing Labview 2013 with Labview 2014, do I firstly need to uninstall Labview 2013?

I have just recieved my latest version Labview 2014 CD.

When installing this new version, do I firstly need to uninstall previous Labview versions?

No, you do not.  LabVIEW 2013 and LabVIEW 2014 can be installed side-by-side.  I currently have 8.2, 2013, and 2014 on this computer.  I have at least 4 versions on another computer.

You normally won't want to uninstall older versions of LV. Although upgrading an older project to your most recent version of SW is good practice there are times when you want to leave the vesion where it is.

The reverse, however, is not true.  Once you install one version of LabVIEW, you cannot install an older version without uninstalling everything and "starting over".  Be warned ...

Also, if you open a VI written, say, in LabVIEW 2013 using LabVIEW 2014 and then save it, you will not be able to open it (again) in 2013.  If you need to do so, you need to open it in 2014 and "Save for Previous Version".

Not exactly true.  You can install just an older version of LabVIEW.  I have had LabVIEW 2012, 2013, and 2014 installed on a computer and then installed 8.2.1.  It is all of the support drivers and what not that do not install side-by-side.  So the real lesson here is that if you install an older version of LabVIEW, pray that your current drivers support that version of LabVIEW.  You will need to reinstall the drivers to install the support for the older version of LabVIEW though.  Installing just the support takes hardly any time.

Crossrulz,

     I suspect you are correct if you are only installing LabVIEW without Bells and Whistles.  I can only tell you that I have suffered through numerous (maybe two dozen) "screwups" in doing a multi-version install (this particular PC has 2011, 2012, 2013, and 2014 nervously coexisting), so I make it a Rigid Practice to only install in sequential order ...  As an example, there is only a single Vision and IMAQdx folder (but maybe they come under the heading of "Drivers" ...).

Use Virtual Machines, and avoid the whole question.  I use VMWare, there are others.

Seeing as IMAQdx is a vision driver, it'd certainly make sense that it would be included in the drivers discussion.  You can reinstall this after installing the older versions as long as they're compatible without issue.

The only thing you're prevented from doing in terms of installing older versions of LabVIEW is installing a version that has the SP1 installed.  I'll run into that one telling me I have a newer version installed.  I've installed older versions lots of times.  I'd venture to say the installations I put together go beyond what you'd call bells and whistles.
