However, by default, Visual Studio uses the 32-bit version. There is no option to enable 32-bit applications in current versions of IIS Express. IIS 8 or greater offer both 32-bit and 64-bit options, so you can download that instead. Therefore the 64-bit version of ACE will not work with it. IIS Express 7.5 only comes as a 32-bit application. Locate the Enable 32-bit Applications entry and change False to True:

If you are using the full version of IIS, you can use the management tool to do this (Control Panel » Administrative Tools » Internet Information Services (IIS) Manager).Ĭlick on Application Pools in the left pane, then select the application pool for the relevant site in the centre pane, and click Advanced Settings on the right: The second option is to change the application pool in IIS to enable 32-bit applications. If you are performing the installation on your development machine, you may also be constrained by the bit-ness of any existing Office installations. You cannot have both the 32- and 64-bit versions of the same provider installed at the same time.
#UNINSTALL MICROSOFT ACCESS DATABASE ENGINE 2010 INSTALL#
If you have the 32-bit version of 2010 or 2016 installed, you need to uninstall it and download and install the 64-bit version instead. If you have the 2007 32-bit version installed, you can simply install the 64-bit version alongside it. First, you can install the 2010 or 2-16 64-bit version. If it doesn't exist, you get the error message that brought you here.

When a call is made to the ACE provider, the 64 bit process will attempt to locate a 64-bit DLL. 64-bit processes cannot load 32-bit DLLs. By default, IIS on a 64-bit operating system will run applications in a 64-bit worker process. If you get this error when trying to use ACE from an ASP.NET application, the most likely cause is that you have installed either one of the 32-bit versions. You need to be careful which option you choose, because a wrong choice here is the most frequent cause for the error message. The 2007 version is only available as a 32-bit component whereas the 20 versions offer both 32 and 64-bit options. The ACE provider is available in three forms: Microsoft Office Access database engine 2007, the Microsoft Access Database Engine 2010 Redistributable and the 2016 Distributable. The ACE provider is not installed on Windows operating systems by default. Alternative option is to download 32-bit Microsoft Access Database Engine 2010 to install with 64-bit MS Office 2016.First, I will dispense with the most obvious reason for the error, and that is that the provider hasn't been registered on the machine on which the application is running.Please note that this approach is not recommended and haven't worked in few instances, so would request you to move to 2 different server approach if possible. Ex: C:\Files\AccessDatabaseEngine.exe /quiet. To do so, download the desired AccessDatabaseEngine.exe or AccessDatabaeEngine_圆4.exe to your PC, open an administrative command prompt, and provide the installation path and switch /quiet. If you are in a scenario where you have both 32-bit and 64-bit processing being performed on the same server that needs to use the ACE data provider, from the Microsoft standpoint, it is recommended to have 2 different servers (1 to process 32-bit mode and the other for 64-bit mode).īut there is an option (workaround) where you can have both the versions installed on the same machine by performing a “/quiet” install of these components from command line.
