Replacing upvc exterior rubber seal gasket without removing window - help

[janz70]

Hi, hope some of you with more experience can help.

We had ivy growing up front of house and when removing it it had managed to attach to part of the upvc window exterior rubber seal between the beading and window and pulled it out.
The window is a massive single pane of approx 7 foot x 3 foot so dont really want to remove it unless I have to.

Can the seal be replaced without taking the window out - any advice and links much appreciated as cant seem to find much online.

PS its interior beaded

Can you post a picture of the seal/ bead?

its round the rental house, going round in a few hours so I will get a photo of it but I think its an E shaped profile - do these exterior seals just push in from the outside or is it a take the window out job to get it in the "groove"

sorry didnt get a photo but it is like this

does anybody know if the window pane will have to removed to fit this type of e seal in its groove or can it be push fit from the outside.

hoping its the later as the window unit is massive.
