No Windos XP support . OMG, just when they made some great changes.
Adobe "forgot" to mention that Lightroom version 4 will not Install on XP.
This is as close as they get on the download page --
"* If you are running a 64-bit version of Windows 7 or Windows Vista,
we recommend downloading the 64-bit version of Lightroom.
To find out if your computer is running a 32-bit or 64-bit version of Windows
in Windows 7 or Windows Vista, open System by clicking the Start button,
right-clicking Computer, and then clicking Properties (under System,
you can view the system type). If your version of Windows is not 64-bit,
or if you are not sure, download the 32-bit version."
I sure didn't get the message from that.
To discover this I had to download the 400 megabyte file,
(tied up my computer for 2 hours) then spent some time
installing it, only to get a message --
"You need a minimum of Vista to run Lightroom"
Goodbye Adobe. You have disappointed me for the last time.
Goodbye Lightroom - just as I was getting persuaded to like
working with you.
Above all else I need a reliable OS.
Sadly IMHO -- XP is the most reliable of the Windows
(But what do I know - I've only been in the OS business
for 25 years. . .) and I'm not giving up reliability.
Yet another set of poor choices by Adobe management.
I really was hoping the Lightroom team could
get Lightroom up to professional standards
- then XP support gets ripped away.
This makes the decision to stay with DXO, Silkypix,
DCraw and RawTherapee easy. They all run on XP
just fine; in my opinion all work better than Lightroom.
