Several versions of Microsoft Access Runtime 365 published by Microsoft between March and April 2026 have been observed to crash when used to read CSV or Excel format data. This can result in Flexera One ITAM and FlexNet Manager Suite business adapters failing to run and terminating abnormally.

This problem has been observed with Microsoft Access Runtime 365 builds newer than 16.0.19127.20302 (version 2508, released October 14, 2025) and older than 16.0.19929.20090 (version 2604, released April 21, 2026). Versions released before and after that have not been observed to encounter problems.

It is recommended that Microsoft Access Runtime 365 versions outside this problematic range should be used on Flexera One ITAM and FlexNet Manager Suite servers in order to avoid issues.
