If you are having difficulty finding the default plugin locations for LABS on Windows it may be worth searching your system for the file names.
When performing a system search it's important that you get the file names correct. Below are a list of the LABS plugin file names that you'll need to identify and search for:
VST2: "LABS (32 bit).dll"
VST3: "LABS (32 bit).vst3"
AAX: "LABS (32 bit).aaxplugin"
VST2: "LABS (64 bit).dll"
VST3: "LABS (64 bit).vst3"
AAX: "LABS (64 bit).aaxplugin"
Searching on Windows
1) In Windows you'll first need to open File Explorer and then browse to your Local Disk. From here you'll note the search box on the right hand side, this is where you'll need to enter the plugin name. In the example I'll be searching for the 64 bit.dll (VST2).
2) Enter the plugin name that you are looking for in the search box. You'll see a "Working on it..." message and a progress bar. Depending on the contents of your system drive, you may need to wait a couple of minutes for this to complete.
3) Once the search is complete you'll then be able to see the specific path that the file is located.
