Batch-Install-VSIX fails to install only if one of VS presented

[dzmitry-lahoda]

I have XML for 11 and 12 VS. But only 12 is installed. And got failure. I think it is just warning cause something will install. And I may maintain one single xml for all VS.

 Visual Studio is not installed or the specified version is not present.

Next scenario is overall bad
We hav 11 VS installed.
XML has

11
11
12
11
11

First 2 items will install, next fail. And have to use choco install xyz --force to reinstall you packages.

I suggest validate whole XML before any actions, fail fast.
Also I suggest to go further with pint all links inside xml to avoid mid failure.

Yet another issue. I started to separate items into different xml to have clear install. Next text becomes repeated

version="11"

If you think that each script should be in different xml for each VS version, then there should be only one version definition on root element. Not sure how chocolatey will work if to run several times same install on different parameters.
