Hi TF_DongDong,

Unified and Professional cannot be installed on the same PC due to incompatibility between databases, you can only have one, if you want to have both I recommend using a virtual machine, anyway, if you want to uninstall Professional correctly, review the following information:

안녕하세요

이 문제에 대한 조언을 얻고 싶었습니다.

현재 Tia Portal V18.0을 다운로드 중이며 WinCC 통합 시뮬레이션을 사용하기 위해 "SIMATIC_WinCC_Unified_PC_V18"를 설치하려고하지만 다음 오류와 함께 설치에 실패합니다.

"WinCC Unified PC V18.0은 현재 설치된 'WinCC Professional' 또는 'WinCC Runtime Professional' 버전과 병행하여 작동할 수 없습니다.

제어판을 통해 'WinCC Professional'을 제거하는 경우 'Siemens Totally Integrated Automation Portal'을 선택하고 마법사를 따르십시오."

이전에 V15.1 WinCC Professional을 다운로드 했으므로 제어판에서 "SIMATIC WinCC Runtime Professional V15.1 UPD6"을 삭제했습니다.

그러나 동일한 문제가 발생하고 포럼에서 문제를 검색하는 동안 " https://support.industry.siemens.com/cs/document/109745000/how-do-uninstall-a-simatic-wincc-professional-or-a-simatic-wincc-runtime-professional-sql-server-instance-?dti=0&lc=en-BR "라는 방법을 발견했습니다 (SIMATIC WinCC Professional 또는 SIMATIC WinCC Runtime Professional SQL Server 인스턴스를 어떻게 제거합니까?) 시도했지만 같은 증상이 나타납니다.

아래 그림과 같이 SIMATIC STEP 7 Professional - WinCC Professional V15.1 Upd6이 추가 정보에서 사라지지 않고 "SIMATIC_WinCC_Unified_PC_V18"가 설치되지 않습니다.

어떤 도움을 주시면 감사하겠습니다.

hello

I was hoping to get some advice on this matter.

I am currently downloading Tia Portal V18.0 and trying to install "SIMATIC_WinCC_Unified_PC_V18" to use WinCC unified simulation but the installation fails with the following error:

"WinCC Unified PC V18.0 cannot operate side-by-side with the currently installed 'WinCC Professional' or 'WinCC Runtime Professional' version.

If uninstalling 'WinCC Professional' via Control Panel, select 'Siemens Totally Integrated Automation Portal' and follow the wizard."

Since I downloaded V15.1 WinCC Professional before, I deleted "SIMATIC WinCC Runtime Professional V15.1 UPD6" from Control Panel.

However, I am having the same problem and while searching for the problem on the forums "https://support.industry.siemens.com/cs/document/109745000/how-do-uninstall-a-simatic-wincc-professional-or-a- simatic-wincc-runtime-professional-sql-server-instance-?dti=0&lc=en-BR" (How do I remove a SIMATIC WinCC Professional or SIMATIC WinCC Runtime Professional SQL Server instance?) I tried, but the same symptoms appears.

As shown below, SIMATIC STEP 7 Professional - WinCC Professional V15.1 Upd6 does not disappear from Additional Information and "SIMATIC_WinCC_Unified_PC_V18" is not installed.

Any help would be appreciated.

Hi TF_DongDong,

Sometimes, even if the SQL instances are uninstalled and the FAQ is followed, some elements are still present on the PC, from personal experience, it is best to start with a clean Windows image, I know it takes time but it is the best option for this problem, believe me
