TMS components pro - intraweb 14.0.46

I am upgrading my environment and upgraded the intraweb to 14.0.46 (has the mobile viewport feature) and upgraded to the TMS v. (the latest) and when trying to install the design time it gives error messages. When trying to use earlier version of TMS IW components with IW 14.0.46 they fail.
Can somebody help me with the TMS-IW14.0.46 issue?

What exact error do you encounter?

Do you follow the steps in INSTALL.TXT to perform the installation? Do you use the correct package files to perform the install?

Issue solved, thanks to Bruno.
When upgrading the intraweb all TMS packages should be removed, and AFTER the intraweb was upgraded ALL TMS components should be recompiled.
Then everything works.
