I have tried to uninstall using CMD and it says invalid or corrupt JAR file for the uninstaller.jar
I have reinstalled the update, several times, manually stopped all Coldfusion services before doing it and it's still stuck in this state.
I'm out of ideas of where to go from here - any help would be much appreciated.
Perhaps you presumed it does not apply to you, but it sounds like it may (and I may rename that section to stand out better to folks who may misconstrue its importance).
I have now managed to install updated 5 with the extra argument and it went through ok. However, I now have a new problem that I can see in FusionReactor which is that it says 'java.lang.NoSuchFieldError: preserveCase'.
I can open the Administrator but Coldfusion is failing to process any application.cfc on my server because of it but I don't have any code that references preserveCase. I don't know if that's a Java problem or a corrupted Coldfusion file problem.
I'd start with clearing the cfclasses folder, if you know what that means. And I'd recommend you stop cf, rename that folder, then start cf. Not only will create the new cfclasses folder for you, but you'll have it for possible postmortem assessment--whether of this or other issues.
I wish Adobe support was as reactive and helpful.
Thanks again.
And you can help others here (since that seems a new problem): what cf update had you been on before update 6?
@S Daugherty, thanks for your kind regards here. Sorry I missed that back in November.
