If you’re reading this article, you’ve probably just installed Dynamics GP (32 bit program) on a 64 bit computer.
These days most new PCs & servers use 64 bits instead of the older 32 bit standard. To maintain compatibility, a 64 bit version of Windows has both 32 bit and 64 bit versions of the ODBC drivers installed. Since Dynamic GP is a 32 bit program, it needs to use the 32 bit version of ODBC when you setup it’s DSN. The same is true for other 32 bit applications.
If you are on a 64 bit computer and add a DSN – by default you are adding a 64 bit DSN. This won’t work with Dynamics GP since it is a 32 bit program. In fact, Dynamics GP won’t recognize a 64 bit DSN at all. If you added the DSN & see it in the list of DSNs, but Dynamics GP does not show the DSN – this article is for you.
Here’s what to do:
Open Windows Explorer, browse to & double-click on:
This opens up the 32 bit ODBC settings – just add the System DSN as usual.
You might want to make a shortcut on the desktop for future use.
The lines above assume that windows is installed on the C: drive. If this is not your scenario, you can use this universal syntax to open the 32 bit ODBC settings from the command line:
This will open the 32 bit ODBC settings from a 64 bit computer. Open up a command prompt & type it in, or click on Start / Run & type it, or click Start & type it into the ‘search programs and files’ box. By using the %windir% variable this will always work regardless of where Windows is installed.
This is a classic example of Microsoft’s Byzantine ‘logic’. We know there’s both 32 bit & 64 bit versions of the ODBC config tool, yet they are both named odbcad32.exe – it gets better. The 32 bit version is stored in the syswow64 folder while the 64 bit version is stored in the system32 folder. Simply put: This is backwards.
