DLL needed for zipping files using VBA that works with 64 bit OS

I've been using the dll file 'xzip.dll' for zipping files.(Made by XStandard). But they don't have a 64 bit version and the 32bit version doesn't work within 64 bit Office. . Anyone have a recommendation. It doesn't have to be freeware.

Or is there now a zipping function or API provided by the 64Bit OS that I can use?

I'm developing this in MSAccess 2010 using VBA. Needs to work for 64Bit office.

Takecoffe: I may look into it, and although I said it does't have to be freeware, $900/yr is way too much.

Alexl40181: In the first link, it looks like it will unzip files, but I also need to zip them.

The second link is the same program I mentioned in my original post. They don't have a 64 bit version. I already asked them.

Alexl40181: Just saw a second link within  your firstexample. I think that may work for me. I'll let you know
I have used the freeware 7zip version here:

They have a 64 bit version.

Here is the code I have used in the past:

    ' 7z.exe,7z.dll Need to have Zip in same location as the Access file
    ' src - must end in \*.*
    ' 7z - 7zip does not erase files on zip, need to erase separately.
    cmd = Chr$(34) & fGetSystemLocation() & "7z.exe" & Chr$(34) & " u -bd -tzip -y -r " & Chr$(34) & ZipFileDir & Chr$(34) & " " & Chr$(34) & src & Chr$(34)
    ExecCmd cmd   ' This waits for execution to finish, this only    r = Shell(cmd)

I hope this helps.

Are you set on using a utilitity or can you use native OS zip functionality to accomplish the task?  I have VBA code for Access to zip files using just the OS.

OM Gang:  I think the second link that Alex40181 provided may work, and it uses the OS. So far it worked on both an XP and Win 7 machine running Access 2003, and 2010 32Bit.  Just need to test it for Office 64Bit and we should be all set.

I won't know for sure till next week. If not, I may have to use the suggestion from by: AndyHoughtonCanada. I'll let you  all know how it turns out.
