Applying the 10.6.30.17 Patch

Note to self:
If you are applying the .17 patch to a computer and see this error:

Error 1304.Error writing to file Payflow_dotNET.dll.  Verify that you have access to that directory.

It has nothing to do with permissions. It means that you don't have the .NET Framework 2.0 installed on that computer. That is a requirement for the .17 patch. All previous versions of 10.6.30.xx only require the 1.1 Framework. And this requirement is right there in the documentation for the patch install as Step #1.
