It's a shame that Support can't pick up my support ticket in a timely way, other than some initial response "try to manually install the upgrade" (which did not work in the first place, just the way I stated in the initial ticket). Subsequently, I sent the reports from the diagnostics tool, but all I hear is utter silence.
So perhaps, someone in here can help me out in a better fashion = forum support service exceeding paid official Support? That would be funny...
(Well, not quite so, since I'm heavily dependent on X1, I'm almost a week without it by now)
Anyway. The trouble I am experiencing is the following:
Previously, version 8.3 was working fine indeed (Win10). First, I ran the 8.4 upgrade installer from within the program. It crashed.
So then, I decided it may be better to manually install this thing - and of course with full Admin rights. That one crashed too....

Ok - so I have an "unexpected error". Whatever that means. Oh - "let's go to the logs"! Errr... those can be found... where? .... thank you so much for not pointing that out either

Not quite. there is no crash log to be found in there (I can conclude this from the "last date modified")
In all: I am stuck, and to make things worse, the old 8.3 install got de-installed by the installer.
So I guess I am left with my 4 Steps to Frustration, instead of 4 Simple Steps to navigate X1Search.
(yes, pun intended

Has anyone experienced a similar situation? If so, were you able to solve this matter, and how?
Any help much appreciated!
Thank you!
