Try running the installer from the downloads or applications folder, its a security issue:

Edit: Or did you move the application via an USB stick or the network after unzipping it? Then chmod +x the executable.

thank you normen

it really was a problem with permissions

I have never seen on Mac Os X

confused :slight_smile:

So, to make this thread useful, how did you solve it?


I’m using iZip archiver by default

I just unpacked the archive with BetterZip and it solves :smiley:

p.s. Mac Os X requires a .dmg containing .app with link to Applications folder or pkg/mpkg for installer. There will be no problems with permissions.

thanks again, sorry my english :slight_smile:

Thanks. The unzip utility that comes with MacOSX preserves the attributes too.
