TYPO3 Core

What do you mean by "fails"?

That what it says if I run it.

Deprecated RTE properties in Page TS Config 
 Update FAILED! 

No deprecated Page TS Config properties were found on page records.

Note that Page TS Config may be included from external files. These were not updated by this wizard. If required, the update will need to be done manually.

I think it should not be shown then.

Will make it a success, but will keep the information maessage.

Patch set 1 of change I0e0919cc02536a12d84da3d37cea64afe3af12e3 has been pushed to the review server.
It is available at http://review.typo3.org/3908

Works now.

What about saving the run state to localconf.php like it is done with install sysext wizard? That way, the wizard would only show up once.

Since deprecated Page TSconfig properties may be found in BE group and BE user records, as well as in external files not searched, nor updated by the wizard, I would like to keep showing the notice and list of deprecated properties until at least release 4.7.
