Help - About

The About command provides information about the running version of Manifold.  The About dialog also checks for any newer versions.



<product name>

The product which is running.  Manifold System Release 9 is cited as Manifold System.  Manifold Viewer is cited as Manifold Viewer.  The illustration above shows an About dialog for Manifold System.


Build number and date of release.

<version status>

Manifold System and Manifold Viewer builds are issued in official builds that are updated every two or three months, with cutting edge builds issued every week to two weeks in between official builds.   Most Manifold users work with cutting edge builds, since they provide new features and bug fixes.  However, to avoid nagging people to update more frequently than they would like, the About dialog checks for official builds only when reporting whether the package is up to date.  


If the build running is the latest official version or a cutting edge build released after the latest official version, the dialog reports Your version is up to date.   If a newer official version is available, the dialog reports New version available, with the new version number as a link that launches the Free Updates page in the default browser.   The Free Updates page provides links to downloads pages for Manifold Release 9 and for Manifold Viewer.

<masked serial number>

Appears for Manifold Release 9 and does not appear for Manifold Viewer.   The serial number used for this installation, with the last dozen digits replaced by X characters, to ensure confidentiality.   Masked serial numbers, that is, serial numbers which have part of the serial number obliterated with X characters, cannot be used for installation or activation.   Masked serial numbers provide enough digits to allow us to keep track of what serial number is installed in which machine.


The CPU that is operating, as reported by Windows.


Reports the number of GPU devices installed in the system, if GPGPU capable, as reported by NVIDIA driver.  The GPU report uses the name CUDA, the name of the NVIDIA GPGPU programming library which the card must support.  


  • If no GPGPU-capable device has been installed in the system, will report Graphics only for the GPU.

  • If one GPGPU capable card is installed in the system, the dialog will report the name of the card (if the card's firmware reports  the name, as almost all modern cards do), together with the CUDA level the card supports.  

  • If more than one GPGPU-capable card has been installed, the dialog reports the number of GPGPU-capable devices but not the card names of each.


The illustration above shows a system with two GPU cards installed that are GPGPU capable and are thus reported as CUDA (2 devices).  To get a report of all cards installed, in Manifold launch a Command Window, enter  the following command, and press the ! run button on the main toolbar.


? CALL SystemGpgpus()


The result table will list all cards by name, together with the CUDA library level they support.


Amount of random access memory installed in the computer system.


The version of Windows that is running, as reported by Windows, including the Release ID for Windows 10+ and Windows Server 2016+ in parentheses.  The illustration above shows a machine that has been upgraded only to the Windows 10 1809 update.


The language in use.   See Localization.  


Appears for Manifold Release 9 and does not appear for Manifold Viewer.  Reports the installation state of the Manifold ODBC driver, and allows installation or removal as desired.


The Manifold ODBC driver is automatically installed when installing Manifold using a Windows Installer installation package, but it is not automatically installed when running a portable installation.  When using a portable installation we must install the Manifold driver using the Help - About dialog.  See the Installations topic for a quick guide to using portable installations and to installing the Manifold ODBC driver.


The report shows if 32-bit or 64-bit ODBC has been installed, whether it is an ODBC driver from an official build or a cutting edge build.  The accessory button allows installation/update/repair and removal.    ODBC status can be reported as:


  • Not installed - The ODBC driver has not been installed

  • Installed - The ODBC driver has been installed into the same location from which Manifold has been launched

  • Installed with mismatching options - The ODBC driver has been  installed into current location, but the install is partial, or damaged, or out-of-date, and thus must be reinstalled/updated.

  • Installed in different location - The ODBC driver has been installed but into a location different from that from which Manifold has been launched.  Typical examples are an ODBC installation that is part of an official build with the current Manifold session launched from a portable installation, or an ODBC installation from one portable installation that is different from the portable installation from which Manifold has been launched.  


We must have administrator rights to install or to remove the Manifold ODBC driver using the accessory button.  If we do not have administrator rights, the button will be disabled, as seen in the illustration above.  To get administrator rights, launch Manifold using Run as administrator.   



For example, to get the illustration above, we right-clicked on manifold.exe, chose Run as administrator to launch Manifold.  The Help - About dialog had the Update button enabled.  We pressed it and the ODBC status immediately switched to Installed, with the button caption changed to Remove.   If we have multiple Manifold sessions launched from the same installation, installing ODBC on any of them will install it for all of them, with no need to restart.  Cool!


An approximate snapshot of the resources currently used by Manifold: the amount of RAM in use, the amount of hard disk in use and the number of files open.


64-bit or 32-bit operation.   Reports Running in 64-bit mode or Running in 32-bit mode.

Buy Manifold 9

Appears for Manifold Viewer and does not appear for Manifold Release 9.   Launches the Manifold Online Store entry page in the default browser.


Close the dialog.



The illustration above shows a typical display for Manifold Viewer.    There is no serial number since Viewer is a free product that does not use serial numbers, and there is no ODBC report since Viewer is a read-only product that does not use read/write ODBC.   The dialog shows an installation on a machine that has an Intel processor and which has two GPGPU capable cards, reported as CUDA (2 devices).   The Buy Manifold 9 button is the only place in Viewer where there is any mention of a commercial product.


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