When I attempt to upgrade Single Sign-On 5.1 to 5.5, I am getting the following error:
CustomAction BootstrapAll returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)
Action ended 11:35:09: InstallFinalize. Return value 3.
This results in a rollback that happens. In searching the docs, there is mention of renaming the CIS folder, which I did, but did not solve the issue. Is anyone else running into this issue when upgrading from 5.1 to 5.5?
