Unfortunately it is not possible to use the product key for the software already installed. Instead, you have the option to purchase the software directly from the manufacturer for about 10 EUR more compared to the Amazon price. No problem - the tax return was saved as a file and I have the "trial" uninstalled in order to install the connection again - awkward but okay.
Double-click on my tax return file now opened WISO and informed me that an update was needed. Here the fun begins:
Send a message to the manufacturer: Why do you need my address, email and phone number to the program allow to load an update right?
Alternatively, you go to the website, is asked again here for all data, denies this and finally pulls the update manually.
So, with fresh update I opened my tax return to see that the many hours of work were in vain. The tax return is deleted. Why? No Idea. The trial version allows the complete filling and storing. Only the printing or the transmission of the declaration must be unlocked.
It's now Sunday, shortly before 09.00 clock. I have better things to do but instead I'm now once again my tax return and very much hope to have preserved some people before purchasing this software ********.
