Just upgraded from 3.32 to 3.42 and got a whole bunch of 'can't open file for writing' errors for all the files in worlds\plugins
Everything else was fine. Am on WinXP Pro with an admin level user, and to be sure it wasn't some bizarre security setting I deleted and re-made the plugins directory and tried again, then tried again just deleting the plugins directory and letting the installer make it itself.
I have a feeling it is a registry entry. You could try uninstalling MUSHclient totally (which should remove its registry entries) and then re-installing. However you will need to re-enter your registration code if you do that.
I concur. I had the same problem with the upgrade.
I did waht Nick mentioned above and I had no problems
with installing afterwards.
This problem is also fixed if you run the installer from the MUSHClient dir, leading me to believe that the problem could be fixed with some error handling in the installer :P
I don't know if its related to the problem or not by any means, but Promonenos' comment reminded me that the file shown was '.\worlds\plugins\<blah>'.
Is it as simple as a typo in the installer script that doesn't have the full path to install to? My understanding of various installers is that you would use a variable to point to the destination, rather than assume you were in the current directory, which the .\ would seem to indicate is the assumption?
Just a thought in the hope of helping.
NSIS has a SetCurrentDir option, which sets the dir to whatever, so you can use relative filenames after that. If Nick gets that from the registry, and the entry is invalid, it will result to a write error. But there are functions which you can use to detect write errors and do whatever you want (such as change the output directory).
