Try this location in the registry :
\HKEY_CURRENT_USER\SOFTWARE\POV-Ray\v3.7\Windows
There should be a \HKEY_CURRENT_USER\SOFTWARE\POV-Ray\v3.7-beta\Windows
entry, or something similar, if version 3.7 beta is installed.
And a \HKEY_CURRENT_USER\SOFTWARE\POV-Ray\v3.6\Windows
if version 3.6 is also installed.
The key entry could be the «Home» value.
Try setting the «Home» value with the same path for both installs.
To be safe, start by renaming the «home» value to something like
«Home-back» before you change anything else. Then, right click and
select «New string value» from the contextual menu and type «Home». That
way, if it don't work, you just delete the edited key and rename the
backed up one to it's original name.
The worst that can happen here is that the version with the altered
entry won't start properly and throw some errors.
==============================================================================
NOT all edition of the registry are benign. DO NOT EVER edit anything
that you are not sure about.
==============================================================================
Never edit anything within \HKEY_CLASSES_ROOT unless you have clear
instructions. (may screw your associations or make some application
unstable)
Same for \HKEY_LOCAL_MACHINE\HARDWARE (may disable some component of the
computer, even prevent it from booting) and \HKEY_USERS (may corrupt a
user's account).
Keys with names similar to «{0ce4991b-e6b3-4b16-b23c-5e0d9250e5d9}» can
render some functionalities or feature unusable if altered. DO NOT touch !
