Hello everyone, I got it !!! Thanks the advice of a Codesys colleague. We have to install the old driver from RTE 3.5 SP17 and then the new one. So...I downgraded my Codesys Control RTE from V3.5.18.40 to RTE 3.5 SP17. So I took the Codesys RTE V3.5.17.30 (unpacked) from the website: https://store.codesys.com/de/codesys-control-rte-sl-bundle.html. For this I uninstalled before the whole Codesys V3.5.18.40 from control panel->programs->programs and features. I also uninstalled the driver and software...
Hello, does someone have an update of this Issue ? I have the same problem. I use Codesys RTE V3.5.11.40 and want to install the Codesys Driver of the CIFX50E-DP under: C:\Program Files\CODESYS\CODESYS Control RTE3\SysDrv3S\SysDrv3S.inf, but become the same message "The Install class is not supported or Invalid". Did someone solve this issue ? Time ago I did this with Codesys RTE V3.5.18.0 and had not problem.
