Unity Accelerator Installation on windows10 64bit failed

I’m trying to reinstall unity Accelerator from windows10 installer.
but Installation failed.
after I follow through all the wizard steps, following message appear

I’m not sure how to solve this?
unity version is 2020.3.20f1
installer is unity-accelerator-app-v1.0.925+g55e634a.exe

It worked when I first installed it.
but when next time try to use Unity Accelerator ,Unity Accelerator dashboard not working.

and so Unity Accerator uninstalled and try to reinstall but above error appear.

I’m also getting this issue. I was following the advice of this thread , mainly because Unity Accelerator did not seem like it was working, so I decided to update it. That didn’t work, so I uninstalled and tried again, which let me pass the page that was not progressing. Now I can’t even reinstall due to this error. I feel like each step of using this feature has been quite frustrating, unfortunately.

It looks like the installer does not properly handle stopping and deleting existing service. Would you be able to try manually stopping and deleting the service before running the new installer?

I’m getting this error, but I’ve already uninstalled the old version of accelerator, so I don’t know how I’d go about stopping it
