Best Practices for deploying VST plugins on Windows

Best Practices (okay… my practices) for deploying VST Plugins on Windows

I’ve seen multiple approaches to installing plugins on Windows. After a number of years of building new Windows-based audio workstations, I have developed the following consistent approach to my plugin installation structure. There are two reasons for this. First, as I move from one machine to another, it is far easier to migrate when the machines are set up in a consistent manner from the old machine to the new machine. Second, my approach embraces the concepts around Windows security in order to avoid needing to ‘run as administrator’ for most application usage. Your mileage may vary, but here’s my take on the process. I would offer up that the install location for RTAS plugins would probably follow this same guidance, but I don’t use and typically won’t install a RTAS plugin on my system.

In today’s age, most of us Windows users (at least 90%) are on a 64-bit version of Windows. For non-business usage, that percentage is yet higher. I would expect for power-audio users, that is really at the 100% mark. I make it a policy to no longer use any 32-bit audio applications or plugins with my system, no exceptions. The incurred overhead and potential instability just isn’t worth it. That being said, I will reference where/how 32-bit plugins should be installed given my approach. Some install packages will require you to install and/or specify a location for 32-bit plugins in order to install the 64-bit versions, so there ARE some 32-big plugins on my systems. I just refuse to use them.

Application Install Location Guidance:

By default, Windows 64 bit applications should install somewhere under :\Program Files\ with some additional path specified by the installer package with either the vendor or application name folders or in some cases both. An example of this would be :\Program Files\Arturia or :\Program Files\KV331\SynthMasterOne

By default, Windows 32 bit applications that are installed on a 64 bit Windows operating system will install to :\Program Files (x86)

Please note that in either case, I would NOT install these application files in the same location as your VST 2 plugins. This is an anti-pattern. Installing the application files in your scanned plugins folders will result in scanning and flagging a significant number of .dll files that are NOT VST plugins. There are other side-effects of this approach that go beyond the scope of this set of best practices. Just suffice it to say “It’s a bad idea”.

Install Locations for VST 2 Plugins

For VST 2 plugins, a location that is ‘accessible’ to all users is a good practice. Personally, I will create a the folder :\users\public\vstplugins on any new system I build. I will then create two additional subfolders, :\users\public\vstplugins\x86 and :\users\public\vstplugins\x64 for 32-bit and 64-bit plugins accordingly. I will then install any VST 2 plugins of the appropriate type (32-bit or 64-bit) into the appropriate folder. This also makes for VERY simple setup of your VST 2 scan folders for ANY audio applications that can load them.

Guidance for VST 3 Plugins

I don’t have any specific guidance here being as the methodology of how discovery is done with VST 3 plugins is VERY different from VST 2 plugins. I simply accept whatever location the installer package wants to put them in.

Installing Present Libraries, Sample Libraries, etc…

Provided the installer supports choosing the location of any preset/sound/sample libraries to be installed (and most do), I always install these under :\users\public\documents. You may or may not choose to subdivide into additional subfolders based on vendor/application/etc… dependent on the particular installer package, however if you are taking a specific approach, DOCUMENT AS YOU GO. If you need to recover or build a new system, you will thank yourself for the guidance. Please note that some libraries come with a significant amount of additional subfolders of their own, so you creating your own subdivisions could create excessively long path names that can cause other types of issues. Do so sparingly and at your own risk.

Backup, Backup, Backup

Lack of a backup strategy with a critical system like your audio workstation is sheer laziness that will one day bite you in the … I personally back up before any significant system change and at least once a week whether I’ve changed anything significant or not. This approach has saved me weeks of effort in the last year alone. Lack of a backup strategy is simply negligence on your part for something you obviously think important enough to spend some significant time on.

I personally have been using Acronis True Image as my backup utility for 15 years with great success. Not only have I done full system restores from images, but occasionally just having the ability to peruse the file system at a date several months in the past to recover just one version of a given file has saved me significant effort in the long run.

Closing Thoughts

I’m hoping some of you find this guidance useful, however I’m sure there are others that have their own consistent standards for this topic. This post was really intended for those who do not yet have a standard, particularly those just starting out in the VST world. This is one right approach, but not the only right approach. Your mileage may vary.

Last but not least, I’m looking to start installing audio software and plugins on MacOS for the first time ever in the near future, so I would love to see a similar post focused on a good, consistent way of approaching this same topic for MacOS from a seasoned Mac user.


Great post for our Windows users. On a Mac, there’s nothing to do - Apple has essentially defined for you where plugins must live

I am installing a new GP PC and that’s the time to think about doing things better than before. I noticed that the default GP install directories are:

C:\Program files\VstPlugins\ (for VST2 plugins)
C:\Program files\Common Files\VST3\ (for VST3 plugins, which seem to be a standard)

In the GP VST2 plugins directory there is no x86 and X64 subdirectories. perhaps I should do it like Arturia does it:


Futhermore, I am wondering what I should choose e.g. for the NI Komplete ? Last time I didn’t succeed to have something clean regarding NI Komplete

I am on Windows.
As for the plugins, I let the installer choose the default locations because I have sometimes chosen other locations and lost access to the presets and banks.
For the sound libraries which are generally large, I choose a location on a different partition of the system or on another hard disk. This avoids having to install again in case of a system crash or reinstallation and above all it reduces the access to the system disk and the number of reads/writes.

I pretty much follow Hermon’s approach. There is a good reason to move sample content (in my case to an external SSD).

For the plug-in itself, I tend to hedge on the side of following the app developer’s default file location/name. There is less chance of me screwing something up and there is less need, in terms of storage space, to deviate from the default installation locations of the plug in. (It is pretty easy to make sure the plug-in manager scans all relevant folders).
