AxCrypt

For managed AxCrypt updates, close the AxCrypt desktop application before launching the installer. The Windows x64 EXE package can return Exit Code 1 when AxCrypt is still running, so Intune, ConfigMgr, RMM, or PSADT deployments should treat AxCrypt as a conflicting process and prompt or close it before the update window. That is safer than relying on repeated retries, because the same installer can keep failing until the encryption client process is closed.

For managed AxCrypt updates, close AxCrypt before launching the installer. If AxCrypt remains open, the update can return Exit Code 1; close the app first and re-run detection after the installer exits.
