How do I install MC12 and keep all of the playlists, ir commands, zones, etc. from my MC11 installation?  Do I install it in the same directory as MC11?  Do I uninstall MC11 first?  I looked on the forum but I couldn't find any anyswers to this, I am sure it is there, but I couldn't find it!  Thanks.

I believe you can backup the MC11 library and then restore it in MC12.  I have both MC11 and MC12 on my machine so, no, you don't have to uninstall MC11.  Their are a few settings - views? - that don't get carried over so you'll have to re-do those... easy enough to do with MC11 still right there.

Hope this helps.

File>Library>Backup Library.

After MC12 install: File>Library>Restore Library. Point MC to: Documents and Settings>Administrator>Application Data>J River>Media Center 11>Library Backups. (you may need to turn on "View Hidden Files" in MS Folder Options)

MC12 will copy the MC11 backup and convert it for use in MC12 and automatically put a new backup file in MC12. The MC11 backup will remain unchanged.

More info can be found at the top of this page, click on Wiki.

along with the library backup, you will need to manually copy some registry settings (from 11 to 12) to  keep column settings, favorites etc.

Depending on how complex these are, i dont think its easy to re-create within MC to 12, the registry method is the only way, but you need to be comfortable with it.

I don't mind recreating some of the things.  I am most concerned about the learned IR commands.  I don't think this gets stored in the library files?  How can I transfer my IR commands over to the new installation, or do I have to relearn everything?  Thanks.

If you haven't given up and done it manually, you can save your settings by manually "hacking" the registry, if you're feeling brave.  I should stress before I even say this... This could completely hose your computer if you don't do it right.  Not for the feint of heart!!

Ok, disclosure finished.  MC saves most of it's non-library specific settings in the Registry under the HKEY_CURRENT_USER\Software\JRiver\Media Center 12 (for v12).  What you'll want to do is copy the registry keys from the HKEY_CURRENT_USER\Software\JRiver\Media Center 11 subkeys to the keys for v12.  This isn't too hard to do.

Before you start, backup your current v12 registry key so that you can restore it if something goes wrong.  Open the registry editor and navigate to: HKEY_CURRENT_USER\Software\JRiver\Media Center 12.  Right click on it in the tree and choose Export.  Save the REG file somewhere safe.

Then, navigate to: HKEY_CURRENT_USER\Software\JRiver\Media Center 11.  Right click on that key and choose Export.  Save the REG file somewhere you can find it.

Open the v11 REG file up using Notepad or some other Text editor.  I use Crimson Editor because it's awesome, but notepad will work just as well.  Then do a find and replace on the file using these terms:

Find: Media Center 11
Replace: Media Center 12

I'd do them one at a time, rather than Replace All.  As you're going through, what you want to do is find all the stuff like this:

Code: [Select]

[HKEY_CURRENT_USER\Software\JRiver\Media Center 11\File Conversion]
And turn it into this:

Code: [Select]

[HKEY_CURRENT_USER\Software\JRiver\Media Center 12\File Conversion]
The next thing I'd do is delete out all the stuff that you really don't need to save from v11.  That way, you're a lot less likely to mess up your v12 install.  You'll want to delete the keys like:

Code: [Select]

[HKEY_CURRENT_USER\Software\JRiver\Media Center 12\Burning]
[HKEY_CURRENT_USER\Software\JRiver\Media Center 12\CD Reader]
[HKEY_CURRENT_USER\Software\JRiver\Media Center 12\Installer]
When you're deleting a key, you have to delete all the subkey info as well.  So, delete the whole block like:

Code: [Select]

And keep the ones like:

[HKEY_CURRENT_USER\Software\JRiver\Media Center 12\Plugins\DSP\MJ DSP\EQ Presets]
[HKEY_CURRENT_USER\Software\JRiver\Media Center 12\Properties]
Then, when you're all done, save it and double click on the REG file (make sure MC12 is closed).  It'll ask you if you're sure.  Say yes and then re-open MC12.  If it crashes, then you did something wrong and restore your REG backup that you made in step 1.
