 ### Dependencies
 
 On Windows Slic3r is built against statically built libraries.
 We provide a prebuilt package of all the needed dependencies.
 The package comes in a several variants:
 
-  - [64 bit, Release mode only](https://bintray.com/vojtechkral/Slic3r-PE/download_file?file_path=destdir-64.7z) (41 MB, 546 MB unpacked)

-  - [32 bit, Release mode only](https://bintray.com/vojtechkral/Slic3r-PE/download_file?file_path=destdir-32.7z) (38 MB, 391 MB unpacked)

+#### Installing using the `INSTALL` project
+
+Slic3r PE can be run from the Visual Studio or from Visual Studio's build directory (`src\Release` or `src\Debug`),
+but for longer-term usage you migth want to install somewhere using the `INSTALL` project.
+By default, this installs into `C:\Program Files\Slic3r`.
+To customize the install path, use the `-DCMAKE_INSTALL_PREFIX=<path of your choice>` when invoking `cmake`.

 ### Building the dependencies package yourself
 
 The dependencies package is built using CMake scripts inside the `deps` subdirectory of Slic3r PE sources.
 (This is intentionally not interconnected with the CMake scripts in the rest of the sources.)
