If I hit "Install Update" on the screen you've posted, the Rig Manager will download to your download folder.
When the download is finished, the updater will be started automatically and check the system for compatibility and then I get a screen where I need to confirm that I allow the updater software to make changes to my system. If you just cancel at this point, you will still have the downloaded update installer in your download folder and can use it whenever you like.
Thank you so much, Martin!
Note to Kemper:
Why not label the tab "Download and Install Update" instead of "Install Update"? IMHO it's misleading as it stands 'cause the general experience of such things is that apps "secretly" place the downloaded file somewhere difficult-to-find, run it straight-away and remove it post-haste.
I heartily agree with Nicky, as I follow the same practice. I have collection of my OS and all programs that I use. For the programs, it's the version that I'm currently using - which may intentionally not be the most recent version. If I need to reinstall, it's important that I know I can do so with the versions that have proven reliable.
I keep notes in each zip's folder and and use a labelling colour scheme to indicate which version I'm currently running, which are problematic and so on. I even use these labels to indicate whether software is free or paid-for.
The aforementioned notes cover such things as, in this case, which version of RM is required for any given Kemper FW update and so on. The information is provided below every download on the Kemper site, so it's not as if it's difficult-to-find.
I'll bet my left nut you have a similar M.O.
The problem with the "Hey, just let the app manage downloading the updates" philosophy is that it's most recent version. I don't trust manufacturers (and with respect, not even the good folks at Kemper) to make that decision for me.
Indeed, that's a practice tailor-made for sheeple, of which I'll never be one.
I really don't know what the fuss is about.... Nobody is forcing anybody to do anything here.
No fuss, G String; we were merely responding to what sounded like a no-choice situation when you told me to, "please update rig manager using the internal update function" in response to my statement (you quoted me), "Hopefully it'll appear in the downloads area very-soon... ". You could've said that the file will be posted later in the downloads section; none of this "panic" would've occurred if you'd responded by saying that it'll be there soon.
Nevertheless, you've later confirmed that indeed it will be there, so thank you so much for that, mate!
