I downloaded Lightroom_5_LS11_win_5_7_1.exe from http://download.adobe.com/pub/adobe/lightroom/win/5.x/Lightroom_5_LS11_win_5_7_1.exe and I have never installed Lr before, but the installation application just cant work.
When I open this .exe file and choose a location and then I click next, this application just stays on "preparing files" and the progress bar also get stuck.
My PC's system is Win 8.1(64-bit) , how to solve this problem??
Same for Photoshop Elements. Same OS and 64 bit
Make sure to run the installer ad Administrator (right-click, runas ...).
