Lightroom 4.3 installed and working. Tried to download and install 4.4. Keep getting message that a problemoccurred while extracting some files. Check for available space and wride priveleges. The setup64 fails to unzip. I have tried this a few times and once got it to unload but then instalation stopped "error in setup". I have tried with virus off, rebooting and closing chrome and lightroom.
The machine is a 64 bit with Windows 7. Have in past updated 4.2 to 4.3
Any other suggestions?
