Just got the following error, when running the Jitsi installer on a
Windows 7 64-bit system with an SSD hard drive: Installation directory
must be on a local hard drive (folder was C:\Program Files\Jitsi) this
happened on both an older 2.4 installer I had lying around, and the
"latest" dated 2015-03-19
The latest installer even showed this error when running the installer
Never heard of that. Besides launching the installer as administrator, google suggests granting the user SYSTEM read,read&execute rights on the .msi. Otherwise: no idea.
