Known issues:

  1. Enabling the optional encryption on the connection strings on Windows 7 / 2008 requires that openPDC Manager be run as administrator or be installed into a non-protected folder such that it can have read/write access to the crypto-key cache. Otherwise an error will be displayed on startup of the openPDC Manager similar to: "Access Denied - Error loading security provider: Failed to decrypt connection string".
  2. The openPDC Console configuration file that gets deployed in v1.4.90 is missing a default setting, running application as administrator once will add the new setting on shutdown. Alternately you can manually update the config file adding the IntegratedSecurity setting from here. Without the setting the console will throw an exception on shutdown. Installing from the nightly build will also correct this error.
  3. Addition of duplicate settings in the connection strings (e.g., manually adding Integrated Security string along with checking the checkbox for this feature) will cause an error to be displayed on startup of openPDC Manager as "Access Denied - Error loading security provider". Make sure there is one key per parameter in the connection string entries until duplicates can be ignored in a future release.
