In our organisation we install softwares on a wide scale. For this command line switches are a must, especially for silent mode installation. Our platforms are all on Windows. The software is one of it's kind and the most excellent that I have seen for compressing and other utilities built in. And we needed to install on all machines and remove winzip. But without the command line switches for silent installation we are finding it difficult. Please help us... Thank you!! With Regards Bejoy
