I've installed multiple versions of codesys from a download, both the .exe and .zip, the installation goes okay but when I open the codesys installer with admin privelages it immediately starts downloading an update, then starts to install the update, but it doesn't complete the installation, it just deletes the installer files in c:\program files (x86)\codesys\apinstaller and never installs a new version. I've ran a repair from the downloaded installer and I can get it to work as long as I don't give admin permissions.
I've done this on my workstation, I've also setup 2 different virtual machines thinking maybe there is some lingering config file, it does it no matter how sanitized the OS is. I've tried running with security software disabled and enabled, it's the same no matter what.
It's been probably 4 months since I used the codesys installer, but it didn't do this back then. Is there a way to set the installer to a certain version and disable updates, or something I can do so the update does what it should?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Do you use 32bit versions of CODESYS? Why not 64bit?
And just use the installer to manage your various versions and add-ons.
Optionally use separate repositories to prevent possible library conflicts.

I'm using the 64 bit version of the engineering software, but the codesys installer seems to be 32 bit.
im trying to use the installer to manage my installations but when I open it with admin privelages it starts an automatic update immediately then deletes itself. I don't know how else to explain this.
This isn't a repository problem, or a problem with the engineering software, it is a problem with the installer.

I would try to use:
https://store.codesys.com/de/codesys-installer.html
this standalone version.
Seems if your version out of SP19 setup have some update problem.
