BTW, I'm in this club too having crossgraded to the Cakewalk Store Sonar Platinum - from Steam X3 Professional.
 
I'm yet to do the actual install ... but have moved swiftly on the ADPaks ;). (One of the reasons was to take advantage of the ReValver Promo (til  Jan 31) ... which turned out to be less enthralling than I thought as it was just the free offering + an XLN Amp ... to get you on the Peavey Appstore bandwagon.
 
Along with the CA-2A T-Type Levelling Amp, there'll be the PC4K S-Type Channel Compressor too, as these two came bundled with the upgrades on Steam and never actually got registered to our Cakewalk Accounts (well - at least not visible on 'My Account')
 
Aside: I got the Concrete Limiter and Expander Gate direct from the Cakewalk Store - these are reflected in 'My Account' OK.
 
(I've also got a couple of the DSF Sound Center Expansion Packs - less concerned about those initially).
 
PS: @Werewindle - if they are still about we should be able to something with the DSF Expansions regardless.
Progs reside under %ProgramData%.
Sfzs an wavs reside under Multisample dirs of DimPro and Rapture.
 

Thanks will have a look but as sonar x3 was a steam download you never know where they got installed. I must have missed something as sound center just freezes when opened. Did notice a lot of copying from Sonar platinum to steam folders when 1st loaded and it has added the steam vst folders to the list. Also had install issues with Dimpro now resolved which may have added to the problem.
 

I was hoping it would simply install to the C:\Programs path, Create new Reg entries and the 2 could coexist ... but it's obviously picking up the Registry entries for Steam X3 which is an issue.
 
I'm not sure when I'll get a window in the immediate future to do the prep/install. I am pretty tech savvy ... but don't expect it to all be plain sailing.
 
I am confident I do know where the DSF packs are installed (assuming C:\, Steam)...

progs (and /images, /patterns) are under
C:\ProgramData\Cakewalk\Cakewalk Sound Center\programs

sfzs / wavs under:
C:\Program Files (x86)\Steam\SteamApps\common\Cakewalk\Vstplugins\Cakewalk Sound Center\Modules\Multisamples
- \Dimension Pro
- \Rapture
(according to pack)    
sfzs (top level)
wavs in sub-directories prefixed with DSF e.g,
- \DSF Guitar Samples
- \DSF Steinway Grand Samples

64bit makes calls to the 32bit location for the sound files (in Steam).
You can distinguish them from factory CSC sounds by e.g, date differences etc.
... but with backups in place it may just be easier to copy the full directories.

Luckily I have a 2nd PC which only has Sonar X3 Producer installed on it via steam, so looks like Just a long slog to cross-check folders contents 1st then move then copy to new locations. Steam was installed on D: drive as the C: drive is SSD and being only 256GB in size only use it for programs where I/O may be an issue which is where Sonar Platinum was installed. And if you don't re-install addictive drums check the VST paths in XLN installer as my 32 bit VST path was altered to 64 bit path. And it wasn't me XLN have confirmed (but not named) that some vendor software alters these paths which manifests as Addictive Drums & Keys are permanently marked as require repair.

Hmmm - you'll have seen some of the other posts about SSDs - good luck.
 
I'd hope that there won't be any issue with Addictive Drums and don't intend to reinstall it. It was always a separate install from Steam to %ProgramFiles% / %ProgramData% and I have my XLN Online Installer VST settings directed off to my custom VST(2) directory anyway. (VST3s are common and external of Steam - but I don't think AD is VST3 anyway).
 
Oh - but I'll check - thanks.

ShellstaX, I doubt it was essential and I am sure there would have been a way around it had I the patience to wait but I ended up having to first uninstall x3pe from steam, platinum still hung at the startup screen, then after a little messing around I just did a backup and fresh installed windows with only platinum to get that working properly, now a matter of waiting to hear back on if/when/how our legitimate purchases can be added to our cake accounts to get all of our gear available in platinum minus the pain in the rear end moving it all around yourself, which I  could probably figure out to, just dont have the desire, I bought it fair and square I should be able to just install it from my cake account IMHO.

I Gotta add Andrew replied to my PM and is going to try to add the products I bought from steam to my cakewalk account page, cant say fairer than that.

I hope Andrew is providing this workaround for all of us

I would send him a pm if I were you since the bakers presence on the forum seems to have faded a little now the release rush has settled a little, I can't see why they wouldn't do it for others in the same boat, I'm nobody special just a.n.other customer :)

Any of you guys have any luck yet? 3 weeks later and "we're sorting it out" is getting old, replied to Andrews PM still nothing :( Starting to wonder how they didn't see this coming treating the same thing on steam as a seperate product, I mean I only want to use the stuff I paid for n all....
