Oracle Client, IIS7 – The specified store provider cannot be found in the configuration, or is not valid.
Ran into this when moving a currently working site to a new directory and setting it up as another site. All IIS and web.config settings matched, so couldn’t figure out why every time I tried to go to a page the needed an Oracle connection I kept getting “The specified store provider cannot be found in the configuration, or is not valid.”
Finally remembered that the App Pool itself has “Advanced Settings”, not just the basic ones which I had already checked. The Oracle Instant Client we’re using is 32 bit, thus the 2nd setting in the App Pool >> Advanced Settings >> Enable 32-Big Applications had to be set to True instead of the default of False.
