Loading GeoMedia WebMap Professional on a 64-bit Operating System
This section provides the system administrator and end user with information on installing and deploying GeoMedia WebMap Professional on a 64-bit operating system. If you run on a 64-bit operating system, such as Windows Vista™ x64, you will need to know the differences discussed in this section. GeoMedia WebMap Professional is a 32-bit application, but it can be run on most 64-bit processors. Loading GeoMedia WebMap Professional on a 64-bit operating system will result in a few changes in folder and license file locations, registry entries, and use of Microsoft Windows tools.
Folder Location—Folder structures for GeoMedia WebMap Professional are different on 32-bit and 64-bit operating systems. On a 32-bit operating system, all GeoMedia WebMap Professional folders and Common Files folders install under C:\Program Files. On a 64-bit operating system, these folders install under C:\Program Files (x86).
License Files—When placing a license file for GeoMedia WebMap Professional on a 64-bit operating system, it must be placed in the folder C:\Program Files (x86)\Common Files\Intergraph\Ingr_Licenses. Note there is no Intergraph folder in C:\Program Files\Common Files on a 64-bit operating system. Like the license folder, GeoMedia WebMap will be placed in C:\Program Files (x86)\GeoMedia WebMap Professional.
Registry Entries—In a similar fashion, GeoMedia WebMap Professional and related registry entries are different on a 64-bit operating system. GeoMedia WebMap Professional HKEY_CURRENT_USER registry entries are unchanged on a 64-bit system, but HKEY_LOCAL_MACHINE registry entries are in a different location. The new location for local machine entries for GeoMedia WebMap Professional on a 64-bit operating system is HKEY_LOCAL_MACHINE > Software > Wow6432Node > Intergraph. If the FlexLM entry for GeoMedia WebMap Professional licensing needs to be modified for license file location or concurrent license server reference, it is also in the new location at HKEY_LOCAL_MACHINE > Software > Wow6432Node > FlexLM license manager.
32-bit Compatible Applications—Any 32-bit compatible operating system application used in conjunction with GeoMedia WebMap Professional has also been relocated on a 64-bit operating system. For example, ODBCad32.exe is the application used to create ODBC DSNs that may be used for various GeoMedia warehouse connections. There are two different ODBCad32.exe files on a 64-bit Windows operating system. One normally resides in C:\Windows\System32, the other in C:\Windows\SysWOW64. Because a 64-bit operating system can run both 32-bit and 64-bit applications, a folder is used to distinguish 32-bit applications from 64-bit applications. Windows applications available from Windows Explorer views reference 64-bit applications. If you need to run a 32-bit Windows application, you must browse to the 32-bit folder, and then run the application from there. The 32-bit Windows applications will be found in C:\Windows\SysWOW64. The 64-bit applications will be found in C:\Windows\System32.
