Qt Creator 2.8.1 crashes on Qt 5.1.1

[Higgs]

Hello all.
I'm new to Qt,started learning about 1 month ago.
In recent days Qt creator behaves strangely,when i want to open Qt project by: "File->Open project",Qt creator crashes and Windows gives me such message:
9618


I'm using Windows 7,32 Bit
Qt projects is in My Documents folder.

Seems to be a message generated from operational system, not properly from QT itself.
Try solve this performing a complete reinstall of QT and its dependencies.

But when I run Qt Creator as an Administrator, it works perfectly,no crashes. Behaves normally.
I'll wait for a while and then try to reinstall Qt.

I could not find any information about that on google.

Added after 10 minutes:

Now i look at event log and what i see is that:
9622

If it runs as administrator but not as an unprivileged user then it is likely to be the result of file/directory permissions. Make sure your project directory (and any directory specified as a shadow build directory) are writable by unprivileged users.

It didn't work :(
I then tried to create second user account, the same privileges as my and Qt creator works fine.
My first account is Power User(where I have problem) and second(that i created for test) account - also Power User.

I don't have any idea how to solve this problem.
