Hey guys, any updates when it will be fixed?

[hvlad]

What you mean by "locked" and what actual problem you have ?

[SkliarOleksandr]

Well, "locked" means I can't delete/overwrite these files after closing fbclient.dll handle. I use fb 4.0.2 embedded under 64bit app. Everything works well but when I close the app (call FreeLibrary(Handle)), some files from fb still remains in memory:
'fb64\ib_util.dll'
'fb64\icudt63.dll'
'fb64\icudt63l.dat'
'fb64\icuin63.dll'
'fb64\icuuc63.dll'
'fb64\intl\fbintl.dll'
'fb64\msvcp140.dll'
'fb64\vcruntime140.dll'

[hvlad]

It is not very easy to unload some of these DLL's. I doubt we can do something with MSVC CRT ones, for example.
Thus, before start impl, I want to be 100% sure it is really needed.
Why you want to delete these files while your app is running ?
Do you need to delete all of these files or some of them (which) ?
