Run the Command Prompt by typing CMD in the Windows search bar at the start menu. You can install the 64-bit engine passively through a command prompt to have them both installed.Įnsure the mso.dll is NOT present in the registry under key below:Ģ010 = "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Common\FilesPaths"Ģ016 = "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\16.0\Common\FilesPaths" Microsoft does not support side by side installation of 64-bit and 32 bit Microsoft Office Solution: You installed a new release of DIAGRAMS, DBWorx (PIDMO), and any other application requiring 64-bit Access and receive the error shown below I’m leaving those alone for now to see how it turns out… but will start carefully pruning these entries (especially the 16.Solution home Solution Articles & Use Cases Installation Error: You cannot install 64-bit Microsoft Access Database engine HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Office\14.0\Common\FilesPaths HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Office\12.0\Common\FilesPaths I also found some for older versions than 16.0 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\REGISTRY\MACHINE\Software\Wow6432Node\Microsoft\Office\16.0\Common\FilesPaths HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\REGISTRY\MACHINE\Software\Microsoft\Office\16.0\Common\FilesPaths □įor Office 16 (Office 365) there isn’t a key similar to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Common\FilesPaths in the 16.0 folder. I did both /passive and /quiet just to be safe. and here I am again doing my annual update of my hated SSIS package and have to refer to this again. I had to use this last year when we were on Office 14 or so…. So I’m posting this on my blog to make this info easier to find for me as well as you. I wrote up a document for this a while back for a client, but I can never remember where I put it. Note: A helpful commenter has informed me that for Access 2016 the switch is /quiet rather than /passive. Delete or rename the mso.dll registry value in the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\14.0\Common\FilesPaths.Follow it with a space and then “/passive” and then hit Enter.Type the file path and file name for your Access Database Engine install file.Option B: Install from the Command Line and Use the Passive Switch It doesn’t have the check to see what other products are on your machine and can co-exist peacefully with the 64-bit 2010 Access engine. The 2007 Access database engine can read the same format, but didn’t have a 64-bit install. Option A: Install the 2007 Office System Driver: Data Connectivity Components There are two options for getting the other version installed. If you try, you will get an error message. You cannot install the 2010 Access database engine with a different processing architecture (bittedness) from your Office install (or install both versions of the 2010 Access database engine) without a workaround. If you have ever attempted this, you know there is a secret. I started by installing the 64-bit Microsoft Access Database Engine 2010 Redistributable. I needed both the 32-bit and the 64-bit adapters to cover my various use cases. The ‘.12.0’ provider is not registered on the local machine. If you try to do either of those things without the ACE OLE DB provider you will get a message like the one below. I sometimes work with SSIS locally to import data from Excel and occasionally do demos with Power BI where I read from an Access database so I needed to install the ACE OLE DB provider. I recently got a new laptop and had to go through the ritual of reinstalling all my programs and drivers.
