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

Hi, previously I has a version of Professional installed, but for some time I had already uninstalled that version.

In this case, how can I check the status of the register, and how i can fix this issue, can you give me some tips?

Hello,

I still have the same trouble, I can't install WinCC unified V19, I've remove Wincc pro V14 but It's not good, I've remove all I've find in the registers about WinCC Pro but I keep the Lock ! Help ! Thanks.

Hello Stephen,

Thanks a lot for answer, I was afraid to have this kind of answer !

Best regards

Hey people from siemens,

could You finally resolve issues with deinstallation?

If can make installer why can't make proper deinstaller?

This is so annoying, going through tutorial how to uninstall tiap, and it doesnt work.

I have removed all siemens programs from pc, and still there is a warning.

this siemens solution is so annoying. cant you do the good job?

It causes to loose lots of time either for trying or for reinstallation of windows.
