Installing LR shouldn't have anything to do with that other program. LR CC by default is installed to the C:\Program Files/Adobe/Adobe Lightroom. It also installs some files in the C:\Users\UserNameOfThePersonThatInstalledIt folder. But none of those files will have any effect on any other program installed on the hard drive.
It could be that lightroom has some files running in " Task Manager
processes" that interfere with other
picture files. I just want to know if it is the case.
I am from Australia my friend is from South Africa.
so any info on problem will be appreciated.
By the way. Have found out the hard way that what cannot happen with
computers usually can.
David there is a reason no one else has replied to your question. That reason is the installation of Lightroom has nothing to do with that other program not functioning any more.
Tell your friend to Reinstall that other program. See if that clears it up.
Hi Thanks for your reply
he did reinstall other program with no results
I do know that sometimes installing 1 program does interfere with
other programs and just because lightroom has not done it before
does not mean it wont do it.
The main problem is that fishsim has faulty jpeg files in it only
since LR installed and it wont load.
Thank you for your advice and help
