SYMPTOMS

Consider the following scenario:
  • You are running a Windows Vista Service Pack 1-based computer.
  • You use a custom Cryptographic Service Provider (CSP) that is based on the winscard module.
When the CSP process closes in this scenario, the SCardReleaseContext function returns a "0x80100004 (SCARD_E_INVALID_PARAMETER)" error code.

CAUSE

This issue is caused by an error in the new cleanup code that is implemented in the winscard module.
