The plugin doesn't show up in my DAWFor VST2 make sure to copy both plugin files into the VST folder which is set in the preferences of your DAW.
For VST3 make sure the plugin is copied into the correct VST3 folder on your system, which is by default:
For 64 bit:
C:\Program Files\Common Files\VST3
For 32 bit:
C:\Program Files (x86)\Common Files\VST3
Also, click the "Re-scan" button if your DAW offers you that. This will re-scan all plugin folders and help to recognize new installed plugins.
A common mistake is to download and install the wrong "bit" version of the plugin. As you will notice, there is 32 bit and 64 bit available. Depending on the combination of your operating system and your DAW, you have to select the correct one, otherwise the plugin won't show up.
Note: A 32 bit software can also run on a 64 bit Windows version, therefore having a 64 bit operating system doesn't necessarily mean that your DAW is also installed as 64 bit. Some older DAWs, like Cubase 5 for instance, were almost only available in 32 bit, but do run on a 64 bit Windows version. Though they need the 32 bit version of the plugin.
If your DAW is installed in the folder Program Files (x86) (with that (x86) at the end), it is a strong indication that it is a 32 bit application, for which you would need the 32 bit plugin version.
If your DAW is installed in the folder Program Files (without (x86)) chances are that it is 64 bit.
Also, taking a look at the about page of your DAW (usually found in Help ➔ About) will most likely tell you whether it is a 64 bit application.
