The most recent cloud upgrade has caused the ICAM Foundation post processors to disappear from the dropdown list when generating NC output interactively. This issue will be corrected in the upcoming Hotfix release.

In the meantime, you can resolve the problem by creating an empty file at the following location:

[3DEXPERIENCE installation path]\\win_b64\\startup\\Manufacturing\\ICAMFoundationPar\\bin\\win64\\QlmLicenseWizard.exe

For most installations, the default path is:

C:\\Program Files\\Dassault Systemes\\B428_Cloud\\win_b64\\startup\\Manufacturing\\ICAMFoundationPar\\bin\\win64\\QlmLicenseWizard.exe

This QlmLicenseWizard.exe file should simply be a blank text file created in Notepad and saved with that exact name.
