Hello Kim and welcome to the board.
First off replacing just this DLL is probably not a good idea unless you have fully tested that replacing it does correct your issues. This is a main file for Microsoft MDAC (Microsoft Data Access Components)
Microsoft Data Access Components (MDAC) 2.8
Here is some code to run that will tell you what the current version is and it's location.
The typical location would be:
C:\Program Files\Common Files\System\ado
Code:
Break On
Dim $SO,$RC,$MDAC,$RB,$CFPath,$MDACVer,$MDACDesc
$SO=SetOption('Explicit','On')
$SO=SetOption('NoVarsInStrings','On')
$SO=SetOption('WrapAtEOL','On')
$MDAC = Trim(ReadValue('HKLM\SOFTWARE\Microsoft\DataAccess','FullInstallVer'))
$RB = Trim(ReadValue('HKLM\SOFTWARE\Microsoft\DataAccess','RollbackVersion'))
$CFPath = ReadValue('HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion', 'CommonFilesDir')
$MDACVer = Trim(GETFILEVERSION ($CFPath + '\System\ado\msado15.dll','BinFileVersion'))
$MDACDesc = Trim(GETFILEVERSION ($CFPath + '\System\ado\msado15.dll','FileDescription'))
? 'MDAC Description: ' + $MDACDesc
? 'MDAC Registry version is: ' + $MDAC
? 'MDAC Registry Rollback is: ' + $RB
? 'MDAC Binary Version is: ' + $MDACVer
? 'File location for MSADO15.DLL is: ' + $CFPath + '\System\ado\'
