Small contribution to Windows Installation (IFTW) FAQ plus a question
For the FAQ
Q: I encountered the following error when running the J2SE installer:
This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package.
Besides the four cases listed, having set IE to "work offline" will also cause the same prompt.
Now my question
Are there files left behind by a Windows Online Installation (IFTW) that I can delete? I have very limited space on C so every little bit would help.
