I purchased the 4_5_0 RadEditor_MOSS web part today, installed it on two servers in exactly the same way.
One of them works fine but on the other one the default content editors (wiki, discussions etc) are not replaced with RadEdit, i get only raw html when i edit an item. I can add the RadEditor web part to a web parts page myself so it has been deployed and actived on the site i am testing...
The only difference i see in the two setups it that on the machine wich is working OK i had RadEditor Lite deployed (and retracted) before i installed the full version.
I suppose i could try and put the light version on the other machine as well then again install the full product (.wsp file) but this is a production server so i hope there is a better solution to the problem ?
EDIT: thanks to another post in the forum, i find out i need te retract and redeploy, now it works, so one needs to deploy the editor twice to get the full version to work !?
