Hey guys !
When I try to install Corona 1.4 RC5, popup show " cannot remove Corona_Release.dll" and " cannot write Corona_Release.dll ".
How to install it succes finally? please help me !
that is probably because your 3dsmax is still running. Try restarting and making sure that for example no vray spawner is running
Ondra ! I try restart computer, but… 
nothing change !
Press windows key+R, and type cmd.
Type command “whoami” This will give you your current user name.
Find the file, that is not being able to be deleted and check in the security tab of the propeties of the file, wether your username has Only read or also write permission for the file.
Maybe you installed it with a different account, multiple users maybe accidently changed write priviledge, you lost admin privilige etc. many reasons, just check to be sure.
Okey ! Let me try ! Thanks so much guys !
I would try using the “just unpack” option and copying the files manually. Maybe this installer is not allowed to do this for some reason?
Maru ! I try to install Corona 1.4 RC5 on 2 computer. First Computer using 3ds max 2016, windows 10. Second Computer using 3ds max 2015. windows 7. Both of them can’t install. I can’t understand @@
try to run installer as admin via right button
Spayer ! I tried this method but don’t succes !
Ok, but have you tried what I suggested in the previous message? Use the “just unpack” option, and then copy the files manually. Does it work?
Download the installer again, and try with the newly downloaded installer.
I don’t understand " just unpack" option ? Can’t you show me clearly Maru! Thanks so much!
