FluentControl installation rollback

Hello!

I am trying to install completely fresh FluentControl 3.5 to a Win11 machine. However at the very end of the installation process the Install Wizard keeps rolling back. Then I am brought to a new window saying that there was an error (with 0 specifications of what kind) and if I want to install FluentControl later then follow the installation process again, with an only pressable button being ‘Finish’.

I have installed the NET 3.5 and also the pre- and post-installation steps work fine.

Could it perhaps be a firewall problem? Maybe something else?

Any help would be appreciated! Thanks!

I believe the issue is due to Win 11 not being a supported OS for FluentControl v3.5,

v3.7 is the latest and is only version Win 11 compatible,

But for example the above post says that even FluentControl 3.4 works on Win 11 with NET 3.5 installed.

Are you installing over any legacy files on the computer or is it a brand new computer with a truly fresh install?

Brand new computer. Never installed any Tecan related software on it.

I’ve only encountered this error when a previous version was causing conflicts.

There could be some kind of IT restriction but not sure.

Then what is the solution if the previous version is installed and/or causing troubles? I wanna know if that would ever happen, because my idea is to try then on some other pc.

can you share the following file:

C:/TecanInstallerMessages.txt

this usually contains information of the status of each installed component - including errors etc

When you install, right click and Run As Admin or make sure you’re on an account with Admin privileges.

In certain instances…

If you’re still having issues and specifically to your question, uninstall all programs in Control Panel’s Add/Remove Programs. Any directory that’s still around labeled Tecan in Program Data folders, Program FIles(x86) folder (and double check Program Files should have the contents deleted or moved into a folder on your desktop. Basically just empty or get those Tecan folders out of those directories.

And then try again.

If that fails, try to review logs or talk to your IT team/Tecan.
