QProcess::start not work in windows 7

[renocz]

Hi, I have a problem

process->start(FEMAG_PATH, femagMacro);
do not work in windows 7 but work perfectly in windows 8


I tried several computers with windows 7 32 and 64 bit. But same error.
Older version of Femag works.

Program Femag alone works in windows 7 good.

Is any parametr in QProcess to set up to solve my issue?

I tried QT 4.7.4 and 4.8.4. Same error.


Could anyone help me or show me the right way to solve this problem?
