I am running win10 on my POS server, I have yet to have an issue with any qt.
If you could give more details as to how your launching it, where its located, etc.
Well I guess the exe is corrupted somehow. No problems with other clients. Tried launching both with and without shortcut, shortcut having parameter -datadir=path\to\datadir. One thing which I noticed is that it was a bit smaller than executable than in November so definitely something has changed.
Sounds like corrupted is the answer. I would grab a fresh download and try again.
Tried several times with the link from first page which links to few pages backwards from this page. No luck.
Thanks for the heads up shall see what is going on! let me know if you were able to figure it out ?
