NOTE: Make sure the extracted ISO is at least 4GB. Depending on the extractor, it may only show up as about 2GB.
If anybody really wants to get this installed:
1. Copy the 'X-treme FX folder' in the root (C:\)
2. Make a copy of the X-treme FX1.dat called X-treme FX2.dat and place it in 'X-treme FX folder'
3. Run the installer. Use the defaults for the VST directory location.
4. After the installer finishes, open the plugin in host. Register it with Keygen.
5. Exit the host. Open the plugin. You may get an error, but can open the presets for FX1 and FX2.
I only played with it a bit, but 9GB on my root isn't gonna cut it so I deleted. Just wanted to see if I could get it to install.
If you really want to use it, could probably have on external drive, can go to the plugin directory and change the shorcuts the installer creates linking to, X-treme FX Presets folder, X-treme FX1.dat and X-treme FX2.dat.
Have Fun!
