I changed my Windows user folder name (and edited the registry), and now Dorico won’t auto-save correctly. I keep getting the following error:
The reason is because it’s still looking for my old username (GIBC-Dan). I changed the default Dorico projects folder to point to a valid location and restarted Dorico, but I keep getting this error message when Dorico attempts to auto-save. I can’t figure out how to solve it. (I don’t want to turn off auto-save).
Thanks in advance for any help.
Highly inadvisable move on Windows. Sorry this is not very helpful, but editing the registry for this is inviting in demons from the other world. And I don’t believe this is an officially sanctioned way.
I moved my Windows 11 home directory to a larger disk, and there are instructions floating around on how to do this - it is not exactly straighforward - but Windows is very ornery when it comes to changing the username. And even after moving you still have to preserve parts of the home directory on C: drive anyway like it or not (a Microsoft mess). I’ll see if I can find some references to help out.
Turn off auto-save, and then turn it back on?
Easiest way is probably to edit %appdata%\Steinberg\Dorico 5\preferences.xml manually - you’re looking for something a bit like this:
<autoSavePath>
<type>string</type>
<value>C:/Users/richa/AppData/Roaming/Steinberg/Dorico 5/AutoSave</value>
</autoSavePath>
Knitting a dangerous web here. Edits of specialized config files on top of edits. Sure it may work, but… This way instability lies.
Actually, editing the auto-save path in the preferences file is safe, as long as you’re careful. The only alternative is to click the Reset to Factory button in the Preferences dialog itself, but the downside of doing that is that you will lose all of the other changes you’ve made to the application’s preferences.
I agree it’s not wise to do oneself; I had an IT-pro friend do it for me. 
That worked, thanks!
The reason I changed the WIndows registry was that I’m constantly switching between computers, opening small files, making tiny edits, and re-exporting… and I haven’t been able to simply use my key command for Export Current Layout because the file structure was different. I had to manually switch to Print mode and re-select the correct destination folder.
But now that the two devices have the same name and exact same file structure, I’m pleased to say it works! This will be a huge time saver and was totally worth the hassle.
