Access fixes released in Version 2604 (Build 16.0.19929.20090)
Unfortunately, version 2604 introduces a serious issue affecting text file imports in Microsoft Access — specifically impacting data type detection and correctness during the import process.
In 16 days, students in Poland will take their final high school exams (Matura), which determine admission to computer science studies. One of the tasks (worth ~20% of the total score) is based on Microsoft Access and requires importing text files as the very first step.
Since this version updates automatically for students, it’s very likely that some of them will be negatively affected during the exam and may end up with significantly worse results this bug.
We’ve described the issue and possible workarounds here:
