Radu, jako že, tohle nedopadne moc dobře mi moc nepomůže. :( . Jel jsem podle tomshardwer: I found below Guideline somewhere• Create a folder name "Temp" under C:\ [This step is important, the folder has to exist.]• Right click the Computer in Start menu and select Properties• Click Advanced System Setting• In System Properties windows, click Advanced tab• Click Environment Variables button• Under User variables list, double click TMP• Change Variable value: from "%USERPROFILE%\AppData\Local\Temp" to "C:\Temp"• Try to install the programI did as above Guideline but didn't work. Then I tried this 1. Right click on a file2. Click "Run as Administrator"And it worked!That simple it is!
