Microsoft Access Database Engine 2010 64bit installation RRS feed

  • Question

  • We have been developing an application using c#, WPF, visual studio 2012 that requires the usage of Microsoft Access Database Engine 2010, we require this to load in and view CSV, XLS, XLXS files etc.  As our application requires to be an any CPU architecture, we ask the user what version they require – 32 bit or 64 bit.  Some users will require a 64 Bit version as they work with some extremely large datasets that are close to 1GB.

    The purpose of this request is regarding the effect of this engine on an existing install of Office 2010.  First of all, to get the 64 Bit version working, we have to use the /passive command on install, otherwise the user would be required to uninstall Office 2010.  The issue arises that after the engine has installed it breaks Office, Access will no longer open on the host machine, and Excel keeps trying to install new components(If you let them install it makes no difference on next load)  – but does work if the install of new components is cancelled.  We found a workaround which involved changing the registry, however this seems to reset when updates are installed, and is not seen as a good workaround.  Recently on a Windows 8 machine we have noticed the problem affects all Office applications as broke Word – which is completely unacceptable for us.

    We are looking either for a workaround for reading this data in a 64 bit environment, or any advice on how we can solve this issue.  Many thanks in advance.
