GIMP_Extensions_v2.8_latest.exe Causes "libtiff-3.dll is missing" Error at GIMP 2 Startup

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install gimp-2.8.6-setup.exe reboot, start, run, quit.
2. Install GIMP_Extensions_v2.8_latest.exe, reboot, start GIMP 2.
3. See errors below at GIMP 2 startup.

What is the expected output? What do you see instead?
My expected output is an error-free startup of the GIMP 2 application. What I 
see instead is a series of errors that go as follows:

ERROR Window #1-
"Seperate_import.exe-System Error (window)
(X) The program can't start because libtiff-3.dll is missing from your 
computer.  Try reinstalling the program to fix this problem. [OK]"

Then the same Seperate_import.exe-System Error (window) a second time.

Then ERROR Window #2-
"gmic_gimp.exe - Application Error (window)
(X)  The application was unable to start correctly (0xc000007b). Click OK to 
close the application. [OK]"

What version of the product are you using? On what operating system?
Version of GIMP 2 is loaded from gimp-2.8.6-setup.exe. My operating system is 
Windows 7 Home Premium (C)2009, SPK1.

Please provide any additional information below.

Got the same issue. I think the issue is with the new 2.8.6 bugfix release of 
Gimp.. I'll try to see if I can't hunt down the necessary libs and gmic 
separately, and then see if it works.

I found a workaround in the meantime. 
Just install the latest version of gmic after gimp-extensions: 
http://registry.gimp.org/node/13469

And then you'll have to get the "libtif-3.dll" dll from the 2.8.4 release of 
gimp, and copy it in your "C:\Program Files\GIMP 2\bin" folder. I suggest 
taking it from a gimp portable install, so you don't accidently overwrite your 
install of gimp : 
https://sourceforge.net/projects/portableapps/files/GIMP%20Portable/Additional%2
0Versions/

After that I'm not sure if its neccessary, but I also downloaded the latest 
version of separate+ :
http://cue.yellowmagic.info/softwares/separate-plus/index.html

And then I extracted the zip and copied the files from the 
"separate+-0.5.8.zip\separate+-0.5.8\bin\win32\" directory into my
"C:\Program Files\GIMP 2\lib\gimp\2.0\plug-ins" folder.

And it loads without any errors now ! However I got like 2 version of gmic 
installed, but GIMP doesn't seem to mind at all..

Derp, I actually forgot to mention that in GIMP 2.8.6, they've removed the 
"libtif-3.dll" library for some reasons.. But I assume you got my meaning.

I think maybe G'MIC and Seperate+ cause the problem.

I can confirm that these errors occur on a Win 7 x64 system, with GIMP 
Extensions v2.8.20130215 and that the issue can be resolved by working around 
the G'MIC and Separate+ plugins.

One clean method to work around the issue on a fresh install is simply to not 
install G'MIC and Separate+ during your installation of GIMP Extensions (i.e., 
clear their respective check boxes under Plugins in the installation dialog 
box). GIMP 2.8 will should open without errors after this install.

Then follow PsyComma's advice and install the latest versions of each of the 
extra plugins:

G'MIC (tested with version 1.5.5.0):
http://registry.gimp.org/node/13469
G'MIC installs automatically by running the exe installer.

Separate+ (tested with version 0.5.8 win32 binaries only version):
http://cue.yellowmagic.info/softwares/separate-plus/index.html
To install Separate+, follow the instructions in the readme file after 
unzipping the folder. Basically, you should just copy the "bin\win32" folder 
into (one of) your plugins folder, which you can find by checking Preferences 
-> Folders -> Plugins.

And that's it. No duplicate plugins, no errors, everything clean.

This Separate+ plug-in is including libtiff3.dll, install this plugin you can 
launch GIMP 2.8.6 without the notice about absence of libtiff3.dll.

I was able to work around the missing libtiff3.dll by copying libtiff-5.dll to 
libtiff3.dll.

"I was able to work around the missing libtiff3.dll by copying libtiff-5.dll to 
libtiff3.dll."

I strongly recommend against that. I'm not aware of the specifics of that 
library, but being a C/C++ programmer with some experience, the interface for 
the library might differ from one version to the other. 

So even if it seems to work, its possible one days you'll get segmentation 
faults or null pointer exceptions, because a function in the old dll isn't in 
the new one, or one function was removed and thus another isn't at the same 
place in the dll..

You should really get the right version, to avoid yourself future headaches !
