Error when starting GW2
I can’t offer much help, but just know you’re not alone, I’m having the same issue trying to update. All I can say is try launching the repair and see if that works. Good luck!
This has been happening to me as well.
Every update, the client crashes while downloading. Every time, I usually fix it by downloading a new client installer, copying the file into the GW2 folder in programs and renaming it Gw2.exe
After that, everything seems to always updates for me but I don’t know why the game does this after every update.
