I have Lightroom 3.0 installed on my external hard drive which I access always on the same USB port on my laptop. After 30 hours of editing I unplugged the device thinking it was safe. My laptop got hit by a virus that just messed my entire laptop up causing me to take it to best buy where they supposedly wiped my laptop and then reloaded it with a new OS. One that looks totally different to me but I did not think this was going to affect my L3 on my external harddrive. I plugged in my device to the laptop and get hit with this error when I click on it:
e:\Adobe Photoshop Lightroom3/lightroom.exe
The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command line sxstrace.exe tool for more detail.
