[SOLVED] Qt version issues on Windows

Dear SOFA community,

I was trying to install SOFA on a 64-bit Windows the same way I did it already two times before using VS 2012. Everything seems to work fine, but when I execute runSofa.exe I get the following error message in a pop-up window:

“The program can’t start because Qt3Support4.dll is missing from your computer. Try reinstalling the program to fix this problem.”

The code I use is an official version downloaded in November 2014. However, it is the same code that is running perfectly on two other machines. The ‘qt4win’ folder is placed correctly in the ‘tools’ directory and the QT_QMAKE_EXECUTABLE field was assigned to ‘…/bin/qmake.exe’ during the Cmake (3.0.2) configuration process. I used the pre-compiled version ‘qt4.8.5_msvc2012_x64’ mentioned in the old Wiki.

My first idea for a solution was to add the binary folder of Qt to the PATH environment variable – this already helped in one of my previous installations instead of setting the QT_QMAKE_EXECUTABLE attribute. Unfortunately, it did not help this time as it created a new error message which leaves me even more puzzled:

“Cannot mix incompatible Qt library (version 0x40805) with this library (version 0x40804)”

This time the message does not occur in a pop-up but on the command line. Of course I checked if there are any other Qt versions involved on the PC but could not find anything. One hour of googling for a solution did not lead to a satisfying result either. Most solutions proposed there are for Linux distributions which use Qt for their UI.

I would be very glad if someone could help me with this error. For me it seems quite strange.

Thanks in advance,
Paul
