edit: fixed it with revo-uninstaller and reinstalling again.
I tried the beta client and ticked the option something like 'optain elevated priviliges' to test things out.
And now I can not start Eddie anymore.
Uninstall and reinstall an older version did not work. Several reboots did not work. Portable does not work.
I tried the common fixes deleting the service stuff (this does nothing) and furiously uninstalling/rebooting/installing and trying to find any config file to get rid of that elevated stuff.... This is crazy how hardcoded this is.
Any ideas?
