If my old RPI program does not work after installing WinRPI, what can I do?
Use the WinRPI enhancer described below and in the WinRPI release notes for more details. Basically, this applet allows you to disable WinRPI and go back to the WinDAPI driver for ECC. Ironically, old RPI Windows RPI programs may be the only Windows programs that do not work well with WinRPI to get ECC. Of course, as described above, one only needs to disable WinRPI while using that old RPI program. WinRPI can be re-enabled afterwards using the WinRPI enhancer.
