Installing lightworks 64bit free ver. failed saying: VcRedist installer failed with error code 1.
What should I do so that I can install it?
I'm using windows 7 (I know it's old, but yeah).

Welcome to the forum.

Windows 7 is supported by Lightworks.

Is that the full error code?

Have a look at this thread to see if it solves your issue: www.lwks.com/index.php?option=com_kunena&func=view&catid=21&id=118369&Itemid=81

Thank you. I'll try looking at it.
