[solved] cannot get Qt creator start?
I have tried to install and uninstall QT SDK for at least 10times, but it still does not run on my laptop. My laptop is SONY VAIO F: QC corei7 1.73GHz, 4GB RAM, NVIDIA GT425M 1GB, and it is running Windows 7. The program installs successful, but it take about 10 minutes to start the program. However, if I start to write a program, it will stop automatically. If I open the program in safe mode, it will run normally. Anybody have this problem? Please help me. I take a C++ this semester and the exam will be giving soon. I hope the problem will be solved so I can practice at home. Thanks

This sounds odd. For helping you one needs to know the source and version of the Qt SDK you installed. Did you install the most recent one from here [qt.nokia.com] ?
Did you use the online or offline installer?
Did use the default setup or some selections?
I have a bug report about strange creator issues with Sony computers on windows… it seems that Qt Creator does not at all like to have “\” and “C:\” in the path which some Sony software seems to put there.
Could you please verify that this is not the case for you?
PS: This is the bug report: https://bugreports.qt-project.org/browse/QTCREATORBUG-6501
I down and install both online and offline “Qt SDK 1.2” which is the most recent one from qt.nokia.com, but it did not work. Then I downloaded the Qt SDK 1.1.2, but it still did not work. Now I found out the way to fix it. If I turn off the Wifi before I start the program, it will run normally. After that I can turn on the wifi and still use the Qt creator. Wondering why this happens?
Specifically, this is a good tutorial:
How to set environment variables in Windows 7 [itechtalk.com]
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.
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.
