Partha,
I have been trying to install your Gimp 2.7.4 for a couple of weeks now. It will install okay but I have to click 14 times before it opens. The error says entry point libgimp 2.0-0dll could not be found. I went to the Bin folder and it is in there.

Also, there is no gimp.exe in there except the one in the bin folder. It says in your web page not to open it from there. this is a scrn shot below to what is in the folder.
Anyway, I did try to open it from there when I couldn't find it and this is where I get the 14 errors.

Molly,

Sorry to hear you are having trouble with this.
Did you download the "standard" version? If you did, you simply click on the exe file (it's an installer which sets everything up for you). If you download the portable version, it will also set it up for you (without affecting your path etc.) and then you click on gimprun.exe to run gimp.

Feel free to send me an email and I will walk you through it.

Thanks,
Partha

I don't see a gimprun.exe anywhere, that is what I was looking for. I installed the regular version 32-bit. I have just what you see in the screen shot.

Your screenshot looks fine. that is how the the folder should look.
gimprun.exe is for the portable version, so you can ignore that comment.

Are you clicking on the shortcut created on your desktop to start gimp or some other method? Either way, do you have some plugins that you installed that specifically require gimp 2.6?

When you run gimp for the first time, it will create a folder in your C:/Users/$USERNAME folder. If you have done a fresh install, there should be no reason for any dlls not being found.

It is a fresh install and it did create a folder in my user name right beside the 2.6 folder is 2.7 (C:\Users\Molly\.gimp-2.7)
Everything is there except the gimp-run. The only way I can execute it is use the gimp.exe that is in the bin folder, that must be why I get all those dll errors. I have taken the whole program out completely 3 times and I get the same thing each time I reinstall.

This is the error:
the procedure entry point deflates set header could not be located in the dynamic link library zlib1.dll

Forget about the gimprun.exe. It is used in the portable version only.

There is no gimp.exe file. The main gimp executable is gimp-2.7.exe. it is in the (in your case assuming standard install) c:\Program Files (x86)\gimp-2.7.4\bin folder. If you went through the install process, it would create a shortcut on your desktop. You simply have to click on that to start gimp. Even if you start from the above, since I add the bin directory to the path, there would not be any dll issue.

Can you post at least one of the error messages you are getting (verbatim)?

OK now, we are getting somewhere.

The most common reason for this that some application has put zlib1.dll in your windows system32 directory since Windows is using the system32 version before the one in your path, you have a clash. Do a search from this dll and rename it zlib1.old. zlib1.dll is already included in your gimp version. Now restart gimp and let me know what happens.

I don't know where to find that system directory. BTW, I have Windows7 (64-bit)

If you click on the start button, then there will be a dialog box, where you type in zlib1.dll. Windows will then display all the dlls with this name. Right click each to locate it's properties. Then find the one that is in the windows system32 directory and rename it to zlib1.old.

The windows system32 folder is located in C:\Windows\System32. Yes, this is also true for Windows 64 also. It is possible that an application put the dll in C:\Windows\SysWOW64 folder. We'll tackle that next. However, the above should solve our problem.

I found 3 zlib1.dll and it shows the 3 in partha's folder and user/molly folder. none in system that I can find. I went right down to the Z at the bottom and none by that name.

PM sent

Doesn't matter where you found that dll, what is important is to remove all of them except 1 in the gimp bin (or plugin) folder

some gimp plugin require that dll and so to be safe some author include it (once was even with gmic) but so it is easy get clones and clones conflict.

okay,
I found one just now in C:\Users\Molly\.gimp-2.6\plug-ins and then there is the one in Partha's gimp-2.7. Bin Which one do I rename?

The only one you need is the one in the Gimp bin directory. Since, it's on your path, the other programs will find it. See my PM to you as well.

Molly why rename ? just remove!

If there is one in the gimp-2.6 folder and one in the 2.7 folder they should not conflict.
Keep them both
Check these 4 places in gimp-2.7 for the conflicting zlib file
Windows/System32
programDirectory/gimp-2.7/bin
programDirectory/gimp-2.7/lib/gimp/2.0/plug-ins
UserFolder/.gimp-2.7/plug-ins

If there are more than one of those zlib files keep the one in programDirectory/gimp-2.7/bin and delete the rest.
I do not understand why you get an error on a fresh install unless you added some plug-ins to the user/.gimp-2.7/plug-ins folder along with that dll file.

No, I didn't add anything.
Ok, I just deleted gimp 2.7.4, took out everything that said 2.7.4, hopefully.
I did a new install into Program files.
I checked to see how many zlib1.dll files there are and I came up with 4. I didn't add them or put them there, they came with the installs.

Here is where the 4 are.

C:\Program Files (x86)\Gimp-2.7.4\bin

C:\Program Files (x86)\GIMP-2.6.11\bin

C:\Users\Molly\.gimp-2.7\plug-ins

C:\Users\Molly\.gimp-2.6\plug-ins

zlib1.dll in all 4 places

I disabled the two zlib's from the user folders and now I get only one error when I start up 2.7.4 which is a lot better than 14.

This one.

Woo Hoo, thanks Partha, we fixed it.
I don't have to click out all those pesky errors now.
You are G-reat.
