Determine Microsoft Database AccessEngine Version
access mdb 数据库 引擎 版本 信息
Hi Everyone,
We develop an application that installs on 32 and 64-bit machines. Depending onthe version of MS Office installed, we then install the appropriate MADE(Microsoft Access Database Engine) version. The MADE install runs silently inthe background. If a user uninstalls
our application, the MADE is leftuntouched and remains on the user's computer. An issue arises when the userdoes not have MS Office installed. In this scenario, a user could first installthe 32-bit version of our application, uninstall and then install the
64-bitversion. In which case two things occur:
- Both 32 and 64-bit versions of MADE are now installed on the computer
- Our application does not work
How can we determine what version of MADE that may already exist on theircomputer? Can we tell if it is 32-bit or 64-bit? I have done quite a bit ofsearching to see if I can find a way to determine which version of MADE is alreadyinstalled, but have been unsuccessful
to this point. My goal is to be able torun a check on the MADE (32 or 64-bit) to see if it is possible for theinstallation to continue. If there is a 32-bit version of MADE alreadyinstalled (without MS Office on the computer) then I do not want to install
the64-bit MADE. Obviously, doing so risks having our application not working,along with any other that uses MADE.
Any ideas would be greatly appreciated.
Thanks!

I would check the existance of thefollowing registry keys on 64-bit machines:
For 64-bit:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Access ConnectivityEngine\InstallRoot
For 32-bit:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\14.0\AccessConnectivity Engine\InstallRoot
