Help with some Regex (VB.net)

I hope someone can help me here. I'm using some regex in VB.net to pull out some text in a string. The text contains "v=" and then the version number. Here is the RegEx I'm using:

v(\d+).(\d+)

Code (markup):

This works fine when the string is something like v1.8 or v9.3...However, not when trying to pull double digits like v10.4 or v20.9...Any idea how this regex would be updated to look for double digits instead? I've tried the following:

v(\d+)(\d+).(\d+)

Code (markup):

But it doesn't seem to be working. Am I missing something?

 

v\d*\.\d+

Code (markup):

This will match:

v5.5
v55.55
v555.555
