"Internal Error" and "Invalid flags specified" errors while issuing eToken card

Problem:
The following errors occur while issuing eToken card at a workstation operating under Windows 2008R2/2012/2012R2, Windows 7SP1, Windows 8/8.1:

Internal error

and

Invalid flags specified

Solution:
The errors are conditioned by that the key length in the certificate template used is 512 bits.
It is necessary to increase the key length at least to 1024 bits, as Microsoft blocks RSA certificates with keys less than 1024 bits (see http://support.microsoft.com/kb/2661254/en).
