Please find below a list of software known to cause issues. Also, if there are any other SmartCard readers connected to the computer (other than the Isabel PPR), disconnect them.
After applying the temporary workaround you are advised to contact the software manufacturer to provide a permanent solution and/or to improve the software.
Temporarily deactivating or uninstalling the security software resolves these issues.
