[solved] cannot get Qt creator start?

Did you check the PATH as I suggested yesterday?

With '' in the path creator used to trigger windows to look up a lot of network drives (until yesterday)... so that would explain why stuff works better for you with wifi turned of.

"Google":http://google.com/?q=path+setup+windows has the necessary instructions.

Specifically, this is a good tutorial:

"How to set environment variables in Windows 7":http://www.itechtalk.com/thread3595.html

If your variable has gotten kind of long, it's inconvenient to edit in the line editor provided by Windows, so I copy the string to something like WordPad and edit it there, and then paste it back into the line editor.

Thanks for all the help. I actually don't know what I have to put in the PATH. I'll ask my instructor or my friends tomorrow.

If I'm understanding the comments above, your PATH variable probably contains the right items, but Qt is getting confused by the "" path delimiters. If you replace every occurrence of "" with "/" you might get some different results. It's a quick fix to try, anyway.

I replaced all the "" with "/", but Qt still does not run. I will have to turn off wifi if I want to use Qt.

No, PATH is a variable handled by windows and it needs to have '' in it. Do not replace '' with '/' everywhere!

There was a problem in Qt Creator that made it handle a entry in PATH containing only a backslash incorrectly. If you have an "" as one element in your PATH then the startup is slow. Please make sure PATH does not start with ";" as the very first characters, does not end with ";" as the very last characters and does not contain ";;" in all the other places. Either remove this part completely or replace it with "C:" (plus ';' in front/after it, depending on position in the PATH string).

So far all people running into this issue were using Sony VAIO laptops, so most likely some utility specific to this series of laptops adds "" as one directory to the PATH.

Thanks. I did it. now I can run Qt without turn off the wifi :))

Great! Please mark this thread as solved then by prepending "[solved]" to the title:-)
