The installer for 2.5.0.0 doesn't behave like prior installs. When at the installer prompt to choose the IDE or Manual Installation, it does not show XE6 or other IDE.
Instructions came up to say to load the BPL's, which there are none.
I had to manually add the path and manually build the run time and design time packages.
Not that I couldn't handle this, this hasn't been the normal behavior of TMS installers.
Upon investigation, we found an issue with the registered version installer for XE6 that we have fixed now. Update v2.5.0.1 is available for download now and will allow you to install directly in XE6 too.
We apologize for this inconvenience.
