Hi all,

I've recently started working with connecting to Excel 2010 files via the Microsoft.ACE.OLEDB.12.0 connection string.

But, what exactly is this "Microsoft.ACE.OLEDB.12.0" (dll, exe etc), and where can I find it's location on my computer?

I need to compare a few boxes to find out which of them has this provider available.
A search of my HDD did not provide any clues...

Thank you!

Ona 64bit OS;

1) If 32bit is installed "ACEOLEDB.DLL" should exists here :

C:\Program Files (x86)\Common Files\Microsoft Shared\OFFICE14\ACEOLEDB.DLL

2) If 64bit is installed "ACEOLEDB.DLL" should exists here :

C:\Program Files\Common Files\Microsoft Shared\OFFICE14\ACEOLEDB.DLL

On a 32bit OS;

"ACEOLEDB.DLL" should exists here :

C:\Program Files\Common Files\Microsoft Shared\OFFICE14\ACEOLEDB.DLL
