    Hi there,

    I'm currently trying to update Unity Accelerator to the most recent version. Unfortunately, at "Ready to Install" where it says "Installation is ready to begin", when I click "Next", nothing happens. No error, not any message, but it also doesn't start the installation.

    The version I have installed (that I'm trying to update) is: Unity Accelerator v1.0.436+g25805e4

    The issue I'm trying to solve is that target platform changes are incredibly slow (up to more than an hour) and consume ridiculous amounts of memory (55GB - on a machine that only has 32GB, so it basically makes it impossible to work on the machine while switching platforms).

    Sunny regards,

    Hi Jashan,

    The Accelerator changed installer-tech since that version you had/have installed and now, so I'm guessing that it's something to do with that. The installer should log its efforts in a temp file, usually in whatever your OS considers your temp directory. e.g. /tmp or C:\Documents And Files\user\Local Settings\Temp and that might give a clue as to what is going wrong.

    You might consider uninstalling the old version and then reinstalling the new version to see if there was some conflict there. The uninstall will leave all the cached data, its database, etc. intact (cachedb directory, etc.) so you shouldn't lose that. Though I guess it wouldn't be the end of the world if you also removed the cached items since it would get repopulated with the next build.

    Hi Gregory, yeah, uninstalling and re-installing fixed it for me.

    I had the same issue, pressing Next didn't do anything.
    Then I uninstalled from "Add or remove programs" and it still didn't work.
    Then I saw that the two unity-accelerator.exe processes are still running, I killed them and deleted the executable files.
    Installation was then able to proceed to next screen but immediately failed at:
    Like, really?
    I found a way to delete a service, ran the installer again.
    It proceeded past the previous point and reported that installation had finished successfully, but then popped one more error for good measure: unity-accelerator-app_2021-09-03_13-58-19.png
    This is the worst installer experience in the world.
