Once you purchase, you receive a confirmation email which includes 2 download links and the product key:
- A link to download the plugin for your 32-bit NLE video software;
- A link to download the plugin for your 64-bit NLE video software.
Do not confuse your editing software with your operating system (OS). Your OS might be 64 bits while your non-linear video editing software can be 32-bit, which is the case with Pinnacle Studio including Studio 16, 17 and Studio 18 32 bit that are only optimized for 64-bit software but remain 32 bits (in this case, use the 32 bit plugin). For Adobe Premiere CS5/6, Sony Vegas 64-bit 9 / 10 Pro ... and now Pinnacle Studio 18 64 bit which are 64-bit applications, use the 64 bit plugin.
During installation, you have to select the plugins you want to install. The window looks like the following, depending on the product to install:

CAUTION: If you do not see your favorite NLE plugin in the selection window, it's because you are perhaps trying to install a bad version...

Open your eyes!
