Can I uninstal and reinstall, just putting in my serial number(s)? I have
them ready to type in. It is the same computer.
It will not start. I have Windows 7. Often things will crash, but usually
they will restart. I had to power down when I had a lockup type issue
with an application. LR4 may have been running and been damaged.
But I ran it since that...
If I try a Windows Uninstall and select the fix the installation option
will it run?
Any good information?
You can uninstall completely, reinstall and type in your serial again, no problem.
Make sure to run the installer as Administrator.
Post the error message you get and some more details on the crashing if you run into it again.
And if re-installing doesn't solve your problems, try resetting the LR preferences file as per here:
