Yes, I must admit - I did not even dare to look into this log.
I thought it failed because v1.6.0-rc3 install process did not look like v1.5.17 installs, - no license acceptance, no anything.
Now, seeing that to use Cryptomator v1.5.17 I must dismantle all my defences (to disable SRP, to log-in as an admin), I tried to do so with v1.6.0-rc3, and it actually installed.
However, it did not appear under the letter C, it got itself into the letter U - as an “Unknown” program.
Starting it with administrative rights I could create a vault at https://wd.mfd.sk, unlock it, reveal its’ drive - and store a file there.
Looks like v1.6.0-rc3 works - for administrators it is.
I’ll ask here - will it work for a LUA as well? Will it be compatible with a well-disciplined OS?
I mean - both LUA and SRP are essential for me.
