Hello Alex,
Thank you for your message.
I've checked with our developers on the issue - the 193 error means that some Printer Driver related library or an exe file was somehow corrupted, perhaps, by some antivirus software activity. You might try checking the antivirus log files to see if there are any entries that might point to the issue.
Could you please try installing the latest 6.12 Beta 2 version instead and see if the printer driver issue persists? The 6.12 Beta 2 version is available for the download on
this page.
Please let us know if the issue persists when installing the 6.12 Beta 2 version as well.
