Darkglass Ultra version 1.2.0 is typically installed in the C:\Program Files\Neural DSP directory, depending on the user's choice. C:\Program Files\Neural DSP\unins000.exe is the full command line if you want to uninstall Darkglass Ultra version 1.2.0.
Manual: Macintosh HD / Library / Application Support / Neural DSP / Note: The plug-in files are “Universal Binaries", so 32-bit and 64-bit plug-ins are included in the same file/location. The 3.0.0 versions of our plugins are available in 64-bit only. It seems Darkglass products are appearing in more bass rigs every day so it's no surprise that Neural DSP chose to recreate two of the most popular Darkglass pedals in digital form. The B7K Ultra and Vintage Ultra are closely related but have very different tones so they seem to be the ideal duo to package together as a plugin.
