   I have the latest version of wordpress installed. It is running on a windows 2003 server. When I attempt to download and update a plugin using the fuctionallity within wordpress I get the following error.

   Upgrade Plugin
   Downloading update from http://downloads.wordpress.org/plugin/ajaxd-wordpress.1.19.zip
   Unpacking the update
   Incompatible archive: PCLZIP_ERR_MISSING_FILE (-4) : Missing archive file 'C:\WINDOWS\Temp\wpu2AE6.tmp'

   I suspect this is a permission problem or something we need to install in php?

   Thank You

   We have discovered that this was a permission problem in the temp directory we change the temp directory to allow Anonymous Internet User (IUSR) account to have permission to write to the C:\Windows\Temp\ folder.

   However the problem now when you run the update the first time you get the following error.

   Upgrade Plugin
   Downloading update from http://downloads.wordpress.org/plugin/dashboard-widget-manager.zip
   
   Unpacking the update
   
   Deactivating the plugin
   
   Removing the old version of the plugin
   
   Could not remove the old plugin

   If you attempt the second time you get the following error

   Upgrade Plugin
   Downloading update from http://downloads.wordpress.org/plugin/ajaxd-wordpress.1.19.2.zip
   
   Unpacking the update
   
   Could not copy file

   Of course this looks like a permission problem in the plugin dir I will get back to you on this after we play with the server a little more.

   Thank You

   IIS servers are always tricky. WordPress runs best on Apache servers. A LAMP stack is simplest, but WAMP stacks work pretty well too.

   English? LAMP WAMP?

   I have multiple blogs running on Windows, but only one of them causes upgrade problems.

   LAMP = Linux, Apache, MySQL, PHP
   WAMP = Windows, Apache, MySQL, PHP

   WordPress is designed for a LAMP server.

   Hi there,

   I also get this message when I what to upgrade a plugin.

   "Could not remove the old plugin"

   I use windows webserver 2003, IIS, with PHP. WordPress version is 2.7.

   I have read a lot of possible solutions, non of them did work.

   How can I find more detail about the problem? Where can I find log files? And things about temp directories and permissions?

   Thank you!
