I am trying to install the Oracle 12c 64bit client on a Windows 10 64bit PC. Whenever I run the setup it just quickly pops up a DOS window then immediately closes it. No error messages, nothing.
I know there are a few command line switches to ignore the prereq checking, but they don't appear to do anything.
Any tips are greatly appreciated...
The big question is 'what do you want the client for'? Most users can just unzip the Oracle Instant Client package(s) and not need to run an installer. If the tools (not the OS) you use are 64-bit then install the 64-bit Instant Client from here, otherwise if the tools are 32-bit then install the 32-bit Instant Client from here. Generic instructions are at the foot of each page, but check whether your tool etc has its own specific instructions.
The next question is do you really need the old 12c client? Since 19c Oracle Client libraries (including those in Oracle Instant Client) can connect to Oracle Database 11.2 or later, you can probably install the latest-and-greatest Instant Client (or "full" Oracle Client if you really need it).
