Not possible to install WinCC Unified locked by WinCCprofessional (not installed)

[costea88]

Hi, all I have some problems with the installation of WinCC Unified.

When I try to install it, the software tells that it is not possible to install WinCC Unified because it is locked by another version of Simatic WinCC Professional, even if no version of WinCC Professional is installed.

Can anyone tell me what to do in this case?

Thanks
