In case you are interested here are the steps:
Carefully perform the following steps on each 64-bit machine that you need the 64-bit ODBC driver installed on (e.g. Windows 7 64-bit PC or Server 2008 R2). This is ideal when running 64-bit applications that cannot 32-bit ODBC connections to Sage 100 (e.g. Any SQL Server 64-bit edition).
** Note: If you are on version 2013 or 2014 these steps are not necessary. Just select Autorun from the \mas90\Wksetup folder and choose the 64-bit ODBC Driver installation. However you may still want the 3 DLLs (version 4.40.0004) mentioned in Step 2 if the installer lays down the old version 4.40.0002.
1. As a prerequisite install the Microsoft Visual C++ 2010 Redistributable Package (x64) if it is not already installed.
One way to find out is look in C:\Windows\System32 folder for the msvcr100.dll file. If not found, then it is not installed. Click on this link to download and install this package. It supports 64-bit versions of Server 2008, Server 2008 R2, and Windows 7.

2. Unzip the attached file to a temporary folder.
3. Copy the 3 DLLs into C:\Windows\System32 folder
These DLLs are based on version 4.40.0004 which is a bug fix from the 4.40.0002 version shipping with v2013 that causes ""catastrophic error"" when doing SQL Server Linked Server queries.
4. Copy the pvxsec64.dll to the server's \mas90\Home folder
5. Overwrite the pvodbsec.ini file in server's \mas90\Home folder with this one
OR edit the existing pvodbsec.ini and add this line:
DLL64=.\pvxsec64.dll
6. Merge the 5 .reg files into the registry. In other words, just double-click the .reg files one at a time and click OK each time at the message box that appears.
7. At this point you can click on Start and type ODBCAD32 and press Enter. This will bring up the 64-bit ODBC Administrator (from c:\windows\system32). Under the User DSN tab the SOTAMAS90 DSN will be found. If you click Configure you will not receive the setup routines error anymore. Under the System DSN table you will see v450PU6Silent has been created. This is a Silent Connect DSN. You can either edit this to suit your needs or even better create a new one for yourself.
