Hello,
I'm trying to install Codesys SP21p6 (but the error occurs in SP22 too for eg.) but it fails to install ApplicationComposer.
Trying to install myself (version 4.4.0.0 or 4.5.0.0) by clicking 'changing the installation' from the Codesys Installer isn't better.
The only message I get is
"An error occured during the installation: The file [..]/ApplicationComposer.plugin.dll isn't a valid plugin"
How is that? The installation went good the last time before a reinstallation...

However, installing the version 4.3.0.0 seems to be successful without knowing what's the difference.

I already tried to :
- Restart my computer
- Delete all temporary files in C:\ProgramData\CODESYS\Temporary Files
- Download the package from the store
- Compare the ApplicationComposer.plugin.dll from another computer (where the installation is OK) and it's exatly the same

For your information, I can install other packages, such as Codesys CFC

Can you help me? Do you have any idea of what could be the problem?
