PB 12.5   I am trying to save a webserver proxy using .NET

I am getting the error:
"Windows sdk for .net framework 4.0 was not installed."

I installed the sdk:
"InstallationFolder"="C:\\Program Files (x86)\\Microsoft SDKs\\Windows\\v10.0A\\bin\\NETFX 4.8 Tools\\"
I confirmed wsdl.exe was there.

-- I rec'd same error.
I found an Appeon fix for error
https://www.appeon.com/developers/get-help/knowledgebase/windows-sdk-net-framework-40-or-higher-was-not-installed.html

Resolution #1 PB ver 12.5 doesn't have httpclient
Resolution #2 change registry:

In the registry SDK was in:
[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Microsoft SDKs\NETFXSDK\4.8\WinSDK-NetFx40Tools-x86]

It said it had to be in v8.0, I had to copy it to the registry under:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SDKs\Windows\v8.0A\WinSDK-NetFx40Tools-x86]

registry entry:
"ProductVersion"="4.8.03928"
"ComponentName"="Microsoft .NET Framework 4.8 SDK"
"InstallationFolder"="C:\\Program Files (x86)\\Microsoft SDKs\\Windows\\v10.0A\\bin\\NETFX 4.8 Tools\\"

Still doesn't work.

I installed the sdk with admin privileges.
I am running PB with admin privileges.
WSDL.exe is in that directory.

What are my options?  thank you very much
