ColdFusion 10 Mandatory Update

Adobe has announced a mandatory update for ColdFusion 10.  The update replaces the  new code signing certificate due to a potential misuse of the existing certificate.  If you do not apply the update, you will no longer be able to update CF10.  The instructions for installing the update on Windows suck aren’t very clear.  It is so much easier than the instructions indicate.

1. Create a folder on your C drive called CF (not required)
2. Download the Update to the folder you just created (if you did step 1) or other location
3. Run cmd.exe as an administrator (right click, choose run as administrator) REQUIRED
4. Change directory to the download location (cd c:\cf if you used step 1)
5. type cf10_mdt_updt.jar and press enter
6. The installer will start and follow the on screen instructions

UPDATE

I attempted to use these instructions on one of our servers and it kept failing.  In finding the fix, I found out that the Adobe instructions are not  bad, just poorly written (IMHO).  If you are using the defaults and a Windows Server without java installed separately, place the update file in the C:\ColdFusion10\jre\bin folder to ensure that java is available to you.  Change the directory you are working in to your bin folder and type in the name of the update file.  Again, if you are using the defaults, the command line should then read C:\ColdFusion10\jre\bin>java – jar cf10_mdt_updt.jar.
