Retain 3.x
Exchange Module


I installed Retain but forgot to install ISAPI Extensions and ISAPI Filters beforehand. Do I have to wipe the server and start over?


No, you do not have to start over. You can find isapi_redirector_installer.exe in the win32 folder and you can install it from there.  Retain will start working once it is installed completely.
