How well does Blender handle multiple instalations side by side?

I have Blender (latest stable version) installed on my workstation. I want to install the nightly build so that I can have the stereo 3D features for a project that I am working on.

Are there any known problems that I could have by having both installed/running at the same time?

• I tried to run nightly builds along stable versions and never experienced problems with that. – Denis Apr 23 '15 at 23:44
• As long as they are installed in different folders under Blender Foundation, there really shouldn't be any issues – VRM Apr 24 '15 at 1:16
• I have never actually "installed" blender, I just use the zips archives. I have never had a problem with having multiple version of blender. – Vader Apr 24 '15 at 7:19
• You don't really install Blender, you download it, and uncompress it (unzip), and that's an intentional design model, it should run just fine from a flash drive (haven't tried myself though). – Georges D Apr 4 '19 at 11:12

multiple blender versions on one system should be fine.

Personally, I don't update Blender builds more than 2 times a week, often less. Of course if some needed feature is broken and has been fixed in a recent build then i'll update asap. There's no right or wrong way here, it's more about how much effort you want to stick into being on the cutting edge.

The simplest way to do avoid potential collisions is to take control of where your new blender files go. This means not using the installers, but instead unpacking the builds manually and putting them in separate folders.

You can make short-cuts to different Blenders and put them on your desktop, that way loading different instances of blender is easy. Remove the short-cuts of the Blender versions that you don't think you'll need for a while. Use unique icons to quickly identify the Blender (maybe using 3d glasses for the icon in the viewport branch)

Add-ons are an easy issue to get wrong, both locating them and installing. But it doesn't have to be hard. Each version of Blender will look in several locations for /scripts/addon.

If you have a core of preferred addons, the way to only worry about those once is to make a custom add-ons folder, and tell Blender to also look there for addons. In:

• User Preferences > File > Scripts

In this example I have a folder on that path called scripts, inside scripts i have:

scripts/addons
