No help menu on QtCreator 2.2.1

Hello,

Im on Ubuntu 10.04 and decided to upgrade QtCreator to it's latest version (2.2.1). I uninstaled older QtCreator using "Ubuntu Software Center" and I went to Qt website to downloaded directly the QtSDK. No problems installing it.
Now I can compile the project I have been developing but I don't have access to Help menu.
I got the following message:

Quote:

The page could not be found
'qthelp://com.nokia.qtcreator.221/qdoc//doc/index.html'

---

What should I do?

Also, in spite of I have no problems compiling the project, I noticed in Tools>Options>Qt4 menu that Qt PATH isn't found ("qmake does not exists or is not an executable"). I can't call "qmake" from terminal.

Thanks,

我也遇到了楼主å� �æ ·çš„é—®é¢˜ï¼Œæˆ‘æ˜¯è¿ ™æ ·è§£å†³çš„
在我的~/.profileåŠ å…¥
PATH=/opt/QtSDK/Desktop/Qt/473/gcc/bin:$PATH
export PATH
然后在终端 source ~/.profile
就可以用了，如æž� �楼主用的不是bash，� �°±åœ¨.loginä¸*åŠ å…¥

至于帮助文件的é� �®é¢˜ã€‚楼主要手动� �Š 载一下
在 /opt/QtSDK/Document/下有好多qch文件就� �˜¯äº†
