If you are running Windows Vista on your computer, there are some known issues about "not running windows installer".
If you are having troubles with launching the Jivaro.msi file, try to launch the file through a non-NTFS drive, follow these instructions:
- Download an Edge code build (or Brackets, presumably) on a Windows Vista machine.
- Run the installer
- If nothing happens then: Right click > Properties > Unblock, then run it again
- Move the MSI file to a non-NTFS drive, then run it (The "downloaded from Internet" tainting metadata is NTFS-only)
USB keys works as a drive support
If you still can’t get the program to install try right-clicking on the program’s install executable and click “Run as Administrator” to launch the install.
