reinstall operation system

[#1]

I need to reinstall my operation system and reinstall the software. Can I use the same license again?

Yes, but you'll have to activate it again too. As long as you have the serial and control number and internet access (or a LEF file) you shouldn't have any problem.

Hi Gysbert,

It turned out that I had hard drive issue on my computer and can't uninstall QlikView there. So I'm using another computer now. What should I do to use the license from the old computer to this one? Where do I find LEF file? I used seriel and control number for license before.

Thanks,

Carol

If you have the license and control number can you just add them and a new LEF will be created when the license is validated.

Good luck!

when entering the license key by LEF, it says The checksum is invalid... Is that because I've already used in the old computer?
