I bought Vegas back at v13 and have bought upgrades through v20. I also bought the v21 upgrade but had not installed it because I expected to set it up on a new PC. This week the older PC crashed, and I need to install.
I received some useful plug-ins (e.g. Chroma Key Pro) with a few of the upgrades, and would like to retain them. I also don't want to lose any older functions (e.g. applying old Film Effects). So: Do I need to install starting from the original v13? If I simply install v21 on the new PC, will the plug-ins disappear? Will I be stopped from installing the upgrade if there is no prior installation on the PC?
At the moment I'm considering going through every installation in sequence, then uninstalling everything except v20 and v21. Is this tedious process absolutely necessary?
