Access Runtime: 32 bit and 64 bit version

 
Microsoft Access - LogotypeThere are 32 bit and 64 bit versions of the Microsoft Access runtime engines available. It is important that the bitness of your database match the bitness of the Access runtime engine. If you have created your database with the 32 bit version of Access, you must also download and install the 32 bit version of the runtime engine.

You can see in the filename of the Access Runtime installation file which bitness it is compiled to. If it is a 64 bit runtime engine, the filename contains the text "x64". If it is a 32 bit runtime engine, the filename contains either the text "x86" or no CPU information at all.

We have listed below current filenames, bitnesses and download links for some common installations of Access Runtime. If your Access version is not in the list, you can search for it via a search engine.

The bitness of your Visual Installer project file should also match the bitness of your database and the Access Runtime installation file. You can read more in this tip about how to change bitness for a Visual Installer project. We will also explain this further in the main tip page (see section 4 in the tip page).
