"Unable To Find Valid Target Platform" When Installing Notes, Due To a Suspended Installation.
When trying to install Notes, you get the below error:
"Unable to find valid target platform"
Usually this error occurs when the user attempts to install a Notes Fix Pack over a nonexistent base version. A Fix Pack checks for the existence of this folder in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\IBM\Lotus\Expeditor on 32-bit operating systems. If these don't exist, the above error is thrown.
However, in this case, this error occurs when the user tries to install the base version of Notes (8.5.2, 8.5.3, etc.)
In one case, this was caused by a pre-existing suspended install of Notes, as seen in the install log:
MSI (c) (7C:FC) [10:21:53:061]: Suspended install detected. Resuming.
