Gimp 2.8 gzdirect problem

This simple solution should fix the problem: "The procedure entry point gzdirect could not be located in the dynamic link library zlib1.dll."

To non-programmers, this error message simply means that your  zlib1.dll is outdated and needs to be replaced.

Somehow, most (if not all) Gimp plugins are using gzdirect which is supposed to be available on  zlib1.dll.

Try checking C:\Windows\System32\ and look for zlib1.dll then rename it to something else, maybe something like  zlib1.dll.old.

So where to get the latest one?  It's actually installed along with Gimp 2.8, but since you have another  zlib1.dll on your Windows' System32 path, Windows is trying to load that copy instead of the copy that Gimp 2.8 has.

Now, re-run Gimp 2.8.

Happy Gimping!

Jenkins: Executing binary from Jenkins script

If anyone of you are having the same problem as detailed on Jenkins forum about not being able to execute any Windows executables from Jenkins Job configuration.  The reason might be that slave-agent.jnlp is running as a service -- and for whatever reason, Windows won't let it run other executables.  To verify if it is the case, try uninstalling the slave-agent.jnlp service -- to do so, use Google -- then try running slave-agent.jnlp as is (meaning, right after executing the code below).

If that didn't solve the problem, sorry but I currently don't have any other solution.
