QProcess, Application found in cache

[kolegs]

Hi,

I'm trying to use QProcess to start 7zip and unpack some files but evertime I get an error Application found in cache. I am using windows 8.

What am I doing wrong?

There is a code:
@ QStringList args;
args << "e" << "-y" << ("-o" + QDir::tempPath()+"/tmp.txt") << packedFilePath;

QProcess p7zip;
QString p7zipPath = QDir::toNativeSeparators("C:/Program\ Files/7-Zip/7z.exe");
p7zip.start(p7zipPath, args);
p7zip.waitForFinished(5000);
qDebug()<<p7zip.errorString();@

and the output:
@Application "??\C:\Program Files\7-Zip\7z.exe" found in cache
"Nieznany blad" ["Unknown error"]@

I tried and it works. Can you check the path and arguments correctly ?

I am sure the paths are correct and with wrong path to 7zip there is an error "no such file or directory"

I think the problem may be related to administrator permission but I am not sure. Its first time I use windows 8 so maybe something changed
