Thanks a lot @Matt && @TravisEz13 for your tips. with your help here is the another working version. 

$Verfile = "C:\Work\Example\versionfile.reg"
$fileContents  = (Get-Content $Verfile | Select -Last 1)

$parts=$fileContents.Split('=')
$versionString = $parts[1].Replace('"','')
$version = [Version]$versionString
$newVersionString = (New-Object -TypeName 'System.Version' -ArgumentList @($version.Major, ($version.Minor+1), $version.Build)).ToString()
(gc $Verfile) -replace "$versionString", "$newVersionString" | sc $Verfile

I assume you can parse the file to the point you get to similar content you give in your question. Additionally, my example is lacking in error handling.

Example

$fileContents =  '"Version"="1.4.0"'

$parts=$fileContents.Split('=')
$versionString = $parts[1].Replace('"','')
$version = [Version]$versionString
$newVersionString = (New-Object -TypeName 'System.Version' -ArgumentList @($version.Major, ($version.Minor+1), $version.Build)).ToString()
$fileContents.Replace($versionString,$newVersionString)

Result

"Version"="1.5.0"
