MS Access Level required: Medium.
Although most systems nowadays are 64-bit by default, it is still very common for Users to have a 32-bit Office installation. One of the reasons could be the smaller footprint by a 32-bit installation, compared to a 64-bit installation, or the cost of upgrading.
As a result it is often found that, an MS Access Application based on 32-bit installation that worked for many years, suddenly don’t work when installed on a 64-bit system.
