Guitar Rig versions - Which one to pick to install..??

Marf

I have multiple "Guitar Rig" versions I can choose to install.
Which version is the best choice to pick to install..??

I have "Guitar Rig 5 - Elements Selection", "Guitar Rig 6 Pro" and "Guitar Rig 7 LE".

My guess is that v5 can be eliminated right away because it's old and only a selection, 2 left to decide... So which one is best to pick, the "v6", because it's a PRO version or the "v7" because it's newer..??

Or is it maybe possible to install "Guitar Rig 6 Pro" and "Guitar Rig 7 LE" both together and use them both without any problems or downside (I'm a Windows user).

SIDENOTE: I have no real guitars, I make my music only with software so it's going to be used for the "effects" on software sounds and plugins!

"Pro" is usually better because it's essentially the full version. However, Guitar Rig 6 is not officially supported anymore and so it won't receive any new updates. You can still use it, though.

"LE" is short for "Learning Edition". It contains more features than the free Player version of Guitar Rig 7, but not everything from "Pro". See this link for an overview of the differences.

Guitar Rig 7 is currently on sale at half price:

You can upgrade from "LE" to "Pro" for ~$75. Maybe worth doing for you?!
