In order to see MS Office connections like Access, you must have MS Office installed on the machine running Construct. You must also have matching bitness (e.g. 32, 64) for MS Office and Construct. If you have a “click-to-run” enterprise version of Microsoft Office, you may not actually have an Access driver installed on your machine. In these cases, you may need to install a driver manually, or even use a file type other than Access. Since this discrepancy can be nuanced, contact support if you’re not sure which version of Office you use.
