Cannot update to 3.40

[rala]

I wanted to make an update but I kinda get only errors.
My operation system is Win10 64bit.

This is the first error:

unsupportedOS.png (68.5 KiB) Viewed 933 times

Well I sometimes get before, that the file is not accessible at its current path (/) with given rights - I also get it with admin rights.

Afterwards (after pressing OK) I get this one:

Then comes the regular License Agreement dialog. After that the installing starts.
Until...

error opening file.png (97.97 KiB) Viewed 933 times

If I press retry ('Wiederholen') the same dialog comes.
Then ignore:

error writing file.png (112.83 KiB) Viewed 933 times

Note: this is not the first which comes directly afterwards.

A set of this dialogs pops up.
I finally canceled the process.

Amy suggestions?

Looks like you are running the installer with Windows' compatibility settings set to pre-Win7 specifically for the installer.

If I take a look at the settings of the exe no compatibility option is enabled.

Which version of Windows 10 are you using?

Are there any third-party virus scanners installed on your machine?

WinVer: 10.0.17763
Virus: no; just Microsoft one itself

The initial error makes absolutely no sense.

In any case, if you install without elevated rights, select an installation directory you have write permissions to.

Try to right-click the installer file and select "Run as Administrator".
