Thanks a lot for your answer.
It is really a license issue, because as soon as I delete all files in ~\00000000-0000-0000-0000-000000000000\License directory, including subdirectory backup, it works fine.
Even if re-creating license from xeroxlicensing.xerox.com/activation, my problem remains the same.
I will contact a license manager to solve that.
For now, it works fine in demo mode (45 days...)
When installing either 184.108.40.206 or 220.127.116.11 FFCore version, french version, on either Windows7 SP1 64bits french or Windows 2012R2 64 bits, Printer configuration tab does not appear in FFCore GUI, and no Components under Workflow configuration is available. So, I cannot create any workflow.
Installation has been tried several times, on 2 very different computers, from scratch OS install, using FreeFlowCore-18.104.22.168-PreInstall_FR, followed by FreeFlowCore-22.214.171.124-Setup or FreeFlowCore-126.96.36.199-Setup french installer. For advanced investigations, I have tried installation with a license, or in Demo mode, without result.
Note that on the same computers, FFCore 188.8.131.52 worke perfectly!
Silverlight is Microsoft Silverlight (64-bit) Version: 5.1.50428.0 .
All other components are installed by the FreeFlowCore-184.108.40.206-PreInstall_FR.exe.
No error messages, no error in MantisDebug.log.
No error in Windows EventViewer.
Has anyone an idea, any way to investigate???
Thanks a lot.
