I was wondering on how to install CMS 5 when CMS 6 is already installed. Can I add new versions to the EPiServer Deployment Center?
I tried to run the installation program for CMS 5 but it crashed with the following error
Launching EPiServerShared.msi /i "C:\incoming\EPiServer CMS 5.2.375.236(2)\EPiServer CMS 5.2.375.236\EPiServerShared.msi" /passive /norestart /lv+ "C:\incoming\EPiServer CMS 5.2.375.236(2)\EPiServer CMS 5.2.375.236\EPiServerShared.msi 2010-03-21T08 06 18 Setup.msi.log" LICENSE_ACCEPTED=1 SQLEXPRESS_INSTALLED=MSSQL10.SQLEXPRESS SQLSERVER_INSTALLED=MSSQL.1msiexec returned 1603Setup.exe Error: 0 : System.Configuration.Install.InstallException: EPiServer Shared Services failed to install.

Aborting the installation.
I'm running on a Vista Ultimate 64 bit.
When I look in the log for the sharedServices install, it fails because cms 6 installed a newer version
MSI (s) (A8:04) [08:06:44:685]: Product: EPiServer Shared 188.8.131.52 -- A newer version of EPiServer Shared Components is already installed.Action ended 08:06:44: PreventDowngrading. Return value 3.
Is it possible to run a cms 5 and cms6 on the same machine at all?
If I run the EPiServerCMS.msi package (from the installation zip) it only installed the installation files and the CMS5 version was available in the Deployment Center and I could install a new site.
Will there be any problem using the CMS 5 site when the shared services is the ss that comes with CMS6 RC1?
I'm running both CMS 5 R2 and CMS 6 RC on the same machine. I would try to install CMS 5 first, then CMS 6. See if that helps.
The error you see is because we added "downgrade" protection in the EPiServerShared installer. EPiServerShared is essentially deployment center, scheduler, indexing and log service. We only allow one installed instance of EPiServerShared and it must never be downgraded to a lower version. What this means is that your solution, just to install EPiServerCMS.msi will do the trick, you already have the latest EPiServerShared installed. What this leads to (i think) is that you won't be able to select "Express" install in the wizard. To get around this, you can replace the EPiServerShared.msi in the R2 installation folder with the one that sits in the CMS 6 installation folder and run setup.exe.
I hope this makes sense.
FYI. Got the same issue when trying to install EPiServer Relate+ after installing EPiServer CMS 6. I ran the EPiServerRelatePlus.msi and it worked. Thanks Fredrik T.
