CleWin 5.4 update

CleWin 5.4 is a free minor update for educational institutes and for commercial customers with a support and update contract. You can download the installer below. Please note that you can choose between a 32-bit and a 64-bit version of the software.

The zip archive only contains a single file: the update utility that will install CleWin 5.4. DO NOT UNINSTALL YOUR CURRENT 5.X VERSION OF CLEWIN. You may uninstall CleWin 5.2 or earlier after installation of version 5.4, or you may continue using it in parallel with CleWin 5.4.
An existing copy of CleWin 5.3 or later will be automatically replaced by the update.
If you have a CodeMeter dongle and license server from PhoeniX BV simply select ‘Cancel’ when prompted for a license file.


The DEPLOF font was designed by David Elata (MEMS Lab, Technion, and kindly provided for other users of CleWin. The font will significantly reduce file sizes and is designed to prevent small features (e.g. the two islands inside an etched ‘8’) to fly off during sacrificial release.
