Installation Problem in Windows 7

[hluling]

I installed this extension for OpenRefine 2.6 on my Mac without a problem.

When I tried to install it on a Windows 7 desktop (for OpenRefine 2.7), I did not see the added functions in the dropdown menu. I followed the instructions (https://github.com/OpenRefine/OpenRefine/wiki/Installing-Extensions). I also tried unzipping the folder into "webapp\extensions." Same problem.

To see whether I installed OpenRefine 2.7 correctly, I tried another extension (https://github.com/sparkica/refine-stats). The installation of refine-stats was successful.

Here is a screenshot of the Command window:

Hi. That would suggest that for some reason some of the files in the extension aren't being found correctly when OpenRefine starts up.

Could you check that in the directory/folder C:/Users/tuf15333/AppData/Roaming/OpenRefine/extensions/refine-gokbutils/master/module/MOD-INF/classes/com/k_int/gokb you can see the folders 'commands', 'functions' and 'operations', and that they in turn contain files ending with '.class' (e.g. AddRowsCommand.class in the commands folder)?

I don't have a Windows machine at hand right now to check this, but I have sometimes seen problems with installing OpenRefine on roaming profiles - which I think maybe what you have here. Another thing you could try (if it is possible) is installing OpenRefine in a non-roaming directory under the C drive - but of course this may not be possible if you don't have administer privileges on the computer.

Best wishes

Thanks for your help.

I installed OpenRefine in a non-roaming directory (C:/openrefine-2.7). Then I installed the extension only in C:/openrefine-2.7/webapp/extensions/refine-gokbutils-master (not in the OpenRefine working directory, which is a roaming directory).

The '.class' files are indeed in C:/openrefine-2.7/webapp/extensions/refine-gokbutils-master/module/MOD-INF/classes/com/k_int/gokb/refine. There are two '.class' files in /refine/commands, three in /refine/functions, and two in /refine/operations.

The same problem exists. Here is a screenshot of the Command window:
