OpenEdge 11.5 SP1 64-Bit overwrites 32-Bit registry

OpenEdge 11.5 SP1 64-Bit overwrites 11.5 32-Bit registry keys

OpenEdge 11.5 32-bit Registry keys/sub-entries point to 11.5 64-bit install after installing the 11.5.1 64-bit Service Pack:

OpenEdge 11.5 32-bit and OpenEdge 11.5 64-bit installed on the same Windows Server.

The OpenEdge Service Pack installer tailors the 32-bit Registry keys: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\PSC 
instead of the 64-bit Registry keys: HKEY_LOCAL_MACHINE\SOFTWARE\PSC 

OpenEdge 11.6.1 corrected the overriding of the 32-bit registry when a Service Pack is installed.

On Windows Servers where OpenEdge 11.5 32-bit and 64-bit OpenEdge products are installed, backup the registry before installing the 11.5 Service Pack and write them back once the Service Pack has successfully been installed:

OpenEdge 11.5 32-bit Registry Keys: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\PSC
OpenEdge 11.5 64-bit Registry Keys: HKEY_LOCAL_MACHINE\SOFTWARE\PSC

Prior restoring the registry, export: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\PSC\PROGRESS\11.5\ServicePack]
and import them back (after the above restore ) as: [HKEY_LOCAL_MACHINE\SOFTWARE\PSC\PROGRESS\11.5\ServicePack]
The entry itself is correct (after the SP1 install), but it needs to go to "64-bit" 11.5 OE Registry.
