BusinessObjects: Public Folder doesn't open in Launch Pad

When you try to open the Public Folder in Launch Pad and it doesn't expand

BusinessObjects 4.0 LaunchPad

I didn't find a real solution for that problem on the internet, so I want to share how to solve it here. In my case it happened on a BO 4.0 platform but may be valid for other versions as well.

When I tried to open the Public Folder in Launch Pad, I just saw the waiting symbol, but it didn't open.

It was a long way to find out that that problem is related to the language settings of the installation. One quick workaround for the problem would be to change the language settings of your browser by adding the language of your BO installation in your settings and rank it to the highest position.

In my case I had to add the English language to my Language Preferences as you can see in the screenshot.

But of course that's just a quick workaround, that can be done from the client.

To solve the problem I had to look into the language directory of the BO installation. I found there two files for crystalreports: one for german (DE) and one for english (EN). I had to delete the german one to have consistent language files in the directory. After restarting tomcat the public folder should show up.
