Identifier ioConfigConnector not defined. CODESYS IDE V3.5SP6 corruption after installation of CODESYS IDE V3.5SP10

Hello,

On this post I report an issue arised after installation of another version of the CODESYS IDE.

On a PC with V3.5SP6 already installed I installed V3.5SP10 to test some newer features. After tests, I uninstalled this version.

Then, applications do not build, and IDE report a lot of errors not related to any Object.

Neither builds a new application, created following the steps in "Online Help: Quickstart > Create and Run a Project".

Just after creation of a new application, the following error is displayed.

C0046: Identifier ioConfigConnector not defined.

If tried to build, the list of errors increases.
Library Manager warns that IoStandard 3.5.10.0 has not been added. <- notice the version number.

Reinstallated of CODESYS IDE V3.5SP6, but this did not solve the issue.

The issue was solved when I uninstalled CODESYS IDE V3.5SP6, found and deleted any CODESYS related files and Windows Registry entries, and installed again.

CODESYS IDE help claims that:

Concepts and Base Components > Profile and Plug-ins
Please note the following with respect to versions of CODESYS and its components:
simultaneous installation of several versions is possible.
different versions of the runtime system and the programming system work together .

did I misunderstand anything?

Thank you
