5.2.6 Connector Install difficulties

[Scott Armistead]

Tried to install 5.2.6, but can not get it to operate correctly
mysql-connector-odbc-5.2.6-winx64.msi

Win 7 with 64-bit machine

Added C:\Program Files\MySQL\Connector ODBC 5.2, and C:\windows\syswow64 to system path

Had msvcr100.dll missing so I installed Microsoft Visual C++ 2010 Redistributable Package, both x86 and x64

myodbc5w.dll and lib are present in C:\Program Files\MySQL\Connector ODBC 5.2

Used the following to register:
myodbc-installer -d -a -n "MySQL ODBC 5.2 Unicode Driver" -t "DRIVER=C:\Program Files\MySQL\Connector ODBC 5.2\myodbc5w.dll;SETUP=C:\Program Files\MySQL\Connector ODBC 5.2\myodbc5S.dll"

I have used 5.2w as my connector for a year or so, and 5.1 before that. I have a MS Access 2007 FE talking to a MySQL BE install on a remote (yet on-campus) server.
The DSN-less connection string I have successfully used for over a year was DRIVER={MySQL ODBC 5.2w Driver} which I simply changed to DRIVER={MySQL ODBC 5.2 Unicode Driver}, however it keeps saying the ODBC call failed.

I have used the GUI provided ODBC manager and am able to create a DSN file and successfully 'test' the connection.
When I use the alternative manager c:\windows\syswow64\odbcad32.exe, I can create a file but not actually set a connection. Nor will it let me edit the file, it simply says 'General error: Invalid DSN file'

More specifically, MS Access gives me the message: Error 3151 ODBC connectin to {MySQL ODBC 5.2 Unicode Driver}qcyce1 failed.
Where qcyce1 is the server name. Here is my entire connection string, where again, the only change was to the DRIVER portion.

ODBC;DRIVER={MySQL ODBC 5.2 Unicode Driver};SERVER=qcyce1;PORT=3306;CONNECTION TIMEOUT=15;COLUMN_SIZE_S32=1DFLT_BIGINT_BIND_STR=1;LANGUAGE=us_english;Option=3;DATABASE=enterprisedata;UID=PartsQuestUser;PWD=PQ;

Any help would be greatly appreciated. I and several others use this application on a daily basis.
