An interesting question was just asked on the MAS 90 LinkedIn Group. One of the users posed the question:
When a customer has 64-bit OS systems, they naturally want to install 64-bit versions of MS Office. All seems fine until one decides to connect to their 32-bit ODBC and are greeted by the “Specified DSN contains and architecture mismatch”. This happened to me – from a 64-bit version of Excel running on a 64-bit OS, selected Data, Other Sources and then selected SOTAMAS90*. (Note the asterisk). Once selected the message displays about the mismatch.
Is there any way around this? It seems that you need a method to tell the 64-bit programs that when they want to use a specific 32-bit ODBC they need to go through SYSWOW64 and call the ODBCAD.EXE. However, I’ve not found any options to force it to the 32-bit ODBC.
The short answer is that 64 bit ODBC drivers are not yet available for Sage 100 ERP .
What most users have done is uninstall any 64 bit apps (usually Microsoft Office 64 Bit) and installing their 32 bit versions.
Our 90 Minds Consulting Group has been tracking this issue since August 2011 and have the following feedback:
– Might be able to in MAS 5.0 but probably pushed to 5.1
– PVX Plus may have a 64 bit ODBC to offer (for a fee) at some point (I think they’re testing)
The present resolution has been to uninstall 64 bit Microsoft and install 32 bit.
Would gladly welcome updates from anyone with different workarounds.
UPDATE: The 64 Bit ODBC Drivers are available from PVX Plus per the following post on the MAS90 LinkedIN group:
To order the driver you can contact firstname.lastname@example.org or call us at 1-888-975-7587 and press 1 for sales.If you want to give it a try it can be downloaded from
(select the 64 bit version — second from the top). It should work using a key of DEMO for testing.
