ElsterFormular "Externe Exception C0FB007F" und WINE

while I was still having a windows machine ElsterFormular was the software i used once a year. now, that i have no windows machine anymore things got a bit more complicated.

i couldn't find a software to submit a 'Umsatzsteuererklärung' (not the 'Umsatzsteuervoranmeldung'), that was free and available for linux and OS X - i couldn't even find one that was available for any of the two operating systems...

that is when WINE came into play (on the linux machine):

• Debian GNU/Linux (mostly stable; but with some testing packages) with Kernel 2.6.22
• wine 0.9.44-1
• ElsterFormular 2006-2007 (8.2.2.0)

and it mostly worked. however, i couldn't transmit data nor could i use the update feature ('Test der Datenübermittlung an das Finanzamt', 'Steuererklärung an das Finanzamt übermitteln...', 'Update von ElsterFormular') but only got

Externe Exception C0FB007F

and the solution was not to reinstall the software (pointed out here and on some other threads here) - i tried that - but to install

• mfc42.dll
• Jet 4.0 Service Pack 8 (SP8) für Windows 95 / 98 / NT 4.0
