--- Comment #23 from Bruno Jesus 00cpxxx@gmail.com --- I have XP SP3 at home and work. At work it works, at home it does not. Then I changed the CryptAcquireContext to set the flag CRYPT_NEWKEYSET and then it works as expected. Not sure this bug is valid (happens in native too), maybe a previous step during the installation was supposed to create the keyset and it failed?
