After a more thorough look, it looks like something more sophisticated
is going wrong.

Your profile name is:

2016. áprilistól

We are taking special precautions to prevent things like spaces or
special characters to be part of the installer filename because some
operating systems have a hard time with those.

Wht's happening here is beyond those precautions though: our precautions
for filename sanitisation use the PHP function iconv for ASCII
transliterisation (i.e. iconv("UTF-8", "US-ASCII//TRANSLIT", ...)

And here we went off rails. Your á and ó are transliterated into a
single quote (') each. So, PHP introduces those single quotes for you
even you don't actually have or want any.

It's a bit beyond me why á does not get transliterated into an "a" , and
ó to "o"; this is a PHP internal decision, and it's not one of the best
IMHO.

Long story short: as an intermediate workaround, you should be able to
get the profile working again by not using the word 'áprilistól' or
anything else with non-ASCII characters in the profile name.
Alternatively, you can define a "custom suffix" to keep the profile
name, but change the installer name directly.

And meanwhile we'll go look a bit deeper into what's happening there to
enable you to use that word in the installer name in the future.

Please let us know if this change of profile name/custom suffix fixes
your immediate problem.

Greetings,

Stefan Winter
