Transfer from Qt 4.8.2 to Qt 5.4 (VS2013)

[FunKDefendeR]

Hello guys,

till now i have used Qt 4.8.2 with VS2010 for programming some small tools.
This worked pretty well, but now I needed to change to VS2013 an because there is no 4.8.2 Version for VS2013 I need to update my Qt Version as well.

This is what i have done:

1. Install qt-unified-windows-x86-2.0.1-online and download Qt 5.2
2. Install qt-vs-addin-1.2.4-opensource
3. Check User Paths C:\Qt\5.4\msvc2013
4. Check includes in code for changes

Now I'm pretty close to compile my code, the last Error is:
LNK1104: File "QtCored4.lib" couldt not be opened.

I cleaned the project I tried to delete some old Files, but the error still occures.

Any Ideas how to fix this issue?

Well, duh, you updated to Qt5. Your linker is telling you it can't find a Qt4 library to link to. Maybe if you changed your link options to link to the Qt5 libraries, it might work better.
