Repairing A Double Glazed Window

[cowfoot]

The glazing bars have pulled away from the glass on at least one of the windows in my new house (last owners clearly not too keen on maintenance, unfortunately). Modern double glazed units so they're just planted on.
Is there a decent fix for this?
I've thought about getting some clear siicone in behind them and clamping it tight.

Don't normally come off if they are stuck on properly in the first place.

Is the bar still straight or has it bent?

Check the glazing bar is not too long as this can stop them pushing back to the glass properly.

Make sure the glass and bar are really clean.

Buy some of this tape, put it on bar and stick back on glass making sure it is pressed firmly back.
