After the upgrade to 2.6.0 via the PortableApps Platform, KeepassXC does not start any more.
The Windows' spinning circle appears for a short time, but other than that, nothing happens.
In the task manager, KeepassXC is shortly visible, then disappears.
Windows 10, 64bit, "E:\PortableApps"
Please try removing keepassxc_local.ini from your KeePassXCPortable\Data\settings folder and running again.
KeePassXC made some strange changes to the settings, changing its location and splitting out a single settings file into two without a clear upgrade path for non-local users. I tried to deal with it as best I could.
Sometimes, the impossible can become possible, if you're awesome!
No, sorry, this did not change the behavior.
After deletion I have a keepassxc.ini and a KeePassXCPortableSettings.ini in the folder.
Delete any further?
The good thing with PortableApps... delete, re-"install", problem solved.
