Manifold Release 9 / Manifold Viewer

This user manual describes both Manifold Release 9 and the free Manifold Viewer based on 9.   See Changes and Additions for what is new in the latest build.


Manifold means Manifold Release 9.  Manifold Release 9 is built on Manifold's Radian spatial database engine.  Radian and Manifold are synonyms in this documentation.   Release 8 means the prior generation of Manifold GIS products.



Product Downloads

Get the latest and best product version from the Product Downloads page for Manifold Release 9 and the Viewer Downloads page for Manifold Viewer.


Manifold does not automatically check for updates.   After installation, at any time check for any newer versions available by launching Manifold and choosing Help - About.   When the About dialog is launched, Manifold will reach out through Internet to check for a new version.    


Run the Latest Build


Always run the latest version of Release 9 or Viewer.   Don't be scared of using Cutting Edge builds.  Run those.  Newer versions of 9 or Viewer are free to download.  If 9 has been activated on a machine, no new activation will be required to un-install an older build and to then install a newer build.   If you cannot open a Release 9 .map or .mxb project file, install the latest version of 9 or Viewer and try again.  Older versions of 9 or Viewer might not be able to open projects created by the very latest build.


The Changes and Additions topic always lists key changes in the latest build. Scan recent changes to get started while updates to documentation are prepared and published.



Manifold Release 9 and Manifold Viewer have different installation options to suit different needs.   For step-by-step installation and activation please see these two topics:




See the Product Downloads web page for Release 9 installation packages.


See the Manifold Viewer downloads web page for Manifold Viewer installation packages.


Administrator Login Required

You must login with genuine and full Administrator privileges to install Manifold.   Being a member of the Administrators group often is not enough as some Windows versions by default do not give full Administrator privileges to users who are members of the Administrators group.  It is best to login as THE Administrator login to install Manifold.  


See the Installations topic for additional important information on hardware and software requirements.



The Manifold GUI uses English by default.  To use other languages for the GUI, provide a localization file as discussed in the Localization topic.   Anyone can create a localization file for a desired language.  See the Manifold website for examples of localization files contributed by users.


64-bit Installations

64-bit Manifold installation packages install both 64-bit and 32-bit versions of the product.  We can launch either or, if we like, we can simultaneously launch both 64-bit and 32-bit versions.   



Run 64-bit Manifold in 64-bit Windows.   Normally, in 64-bit Windows we would always run 64-bit Release 9 or 64-bit Viewer.


Why launch a 32-bit version of Release 9 or Viewer in a 64-bit Windows System?   We usually do that when we need to connect to 32-bit software that is running in 64-bit Windows.  In some cases we may have to launch in 32-bit mode to connect to Microsoft Office formats.   See the Launch in 32-bit Mode topic and the Microsoft Office Formats - MDB, XLS and Friends topic.


Three Letter Extensions

Most file names in Windows end in what usually is called a three letter extension, which is usually three or four letters at the end of the file name following a dot . character.    The three letter extension is one way Windows at times (but not always) keeps track of what a file is supposed to be.    Unfortunately, by default Windows hides the three letter extensions of files and instead tries to associate files with whatever program it thinks should be used to open that file.   That may be helpful for inexpert consumers, but for skilled users it is inconvenient and can be misleading  when working with the many file formats that Manifold and similar products utilize.  tech_tina_sm.png


Tech tip:  Please turn off the hiding of extensions by Windows.  A typical way to do so in most versions of Windows would be from Windows Explorer, choose Tools - Folder options, press the View tab and then in the Advanced Settings pane ensure that the Hide extensions for known file types is unchecked.  Press Apply to Folders and then press OK.  You will then be able to see extensions such as .map and others.  See also the Essay on three letter extensions and why the default hiding of them by Windows is such a bad thing.

Manifold Viewer

Manifold Viewer is a free product from Manifold that is a read-only subset of Release 9.  Viewer has significant limitations compared to Release 9:



Despite the above limitations Viewer retains so many Release 9 user interface commands and functions, like full spatial SQL, full CPU and GPU parallelism, that the same user manual - this user manual -  is used for both Release 9 and Viewer.  Viewer users who read this documentation should keep in mind the above limits.  If a command or menu option does not appear, that is usually because of one of the above limits in Viewer.   In most situations the situation will be clear.    


Manifold does not provide technical support for Manifold Viewer.  Hey, it's free!


To get support on Viewer, read this user manual, watch the videos, or ask questions of other users on the Manifold Forum.

For Manifold Release 8 Licensees

All new Manifold releases utilize Radian technology .map format.   Release 9 or Viewer can open Manifold Release 8 .map files but Release 8 cannot open newer, Release 9 .map files.   


ico_nb_arrow_blue.pngAutomatic conversion:  If we open a Release 8 .map file in Manifold and then Save that .map file it will be saved in newer, Release 9 .map format.  Manifold will warn us the file already exists and will offer to save using an incremented name to avoid overwriting the original Release 8 .map, but if we insist we can use the same file name to overwrite the original Release 8 .map file.  To retain the ability to read the original .map file in Release 8, make sure to save the .map file created by Release 9 using a different name.   Use File - Save As to save under a different name.


ico_nb_arrow_blue.pngAutomatic conversion when Linking:  Linking a Release 8 .map file or creating a new data source based on a Release 8 .map file will also cause that .map file to be converted into Release 9, Radian .map file format.    Make a backup copy of any pre-Radian .map files you wish to retain in the old format before you open them or use them in a Manifold project.


Manifold Release 8 can connect to newer Manifold projects using the Manifold Release 9 ODBC driver.   That facilitates interchange between newer Manifold projects and Release 8.   See the discussion in the Projects and .map Files topic and the Example: Connect to Manifold from Release 8  topic.
