Taiga update failed (1.2.0 to 1.2.1)

[Akamaru]

When I try to update from v1.2.0 to v1.2.1, I got following message

Translated (with Google sry):
Unsupported 16-bit-application
The program or feature "??:\Users\Pinkie\AppData\Roaming\Taiga\TaigaSetup.exe" due an incompatibility with 64-bit versions of Windows do not start or run. Contact the software manufacturer to learn by, whether compatible with 64 bit Windows version is available.

I use Windows 8.1 64-bit

Here's the English version of the same error:

Unsupported 16-Bit Application
The program or feature "??..." cannot start or run due to incompatibity with 64-bit versions of Windows. Please contact the software vendor to ask if a 64-bit Windows compatible version is available.

It doesn't seem to be a common issue, as hundreds of people have updated successfully so far. Could it be because the downloaded file was somehow corrupted for you? First, try updating again. If that doesn't work, go to the installation directory and manually execute TaigaSetup.exe. Finally, you can try downloading the latest setup from the website yourself.

Edit: If you get the same error when you manually execute the setup, could you send me the file so I can examine it?

Okay, updating again doesn't work. Manually execute TaigaSetup.exe doesn't work. So I downloded the setup and this works.
When i try to manually execute TaigaSetup.exe, following message appears:

"This app can not be run on the PC.
Apply to find on the Software Publisher an appropriate version for your PC"

Here is the file

Avira's fault. It apparently prevents the auto-update process of Taiga, replacing the contents of the executable with HTML that says:
