Standalone OpenPetra: initial login fails on Windows

pokorra

@[deleted], you have reported issues with the Standalone installer.

I also got the same report from Frederik, another user interested in OpenPetra.

Here is the error for everyone:
The message box says: "Login failed", "An error occured while trying to connect to the OpenPetra server! For details see the log file: C:\users\<username>\AppData\Roaming\OpenPetra\log30\PetraClient.log"

Frederic gave me that log file, and it complains about not being able to find the file libsodium.dll:

Exception occured: System.TypeInitializationException: Der Typeninitialisierer für "Sodium.SodiumCore" hat eine Ausnahme verursacht. ---> System.DllNotFoundException: Die DLL "libsodium.dll": Das angegebene Modul wurde nicht gefunden.

I thought I found the solution here: https://github.com/adamcaudill/libsodium-net/issues/111#issuecomment-158791421

But that did not solve the issue on the test laptop either.

So I guess the next step is to drop the use of libsodium from the Standalone OpenPetra. It is intended for demo usage anyway. For production I recommend to use Linux for the server and Windows for the client.

If you just want to try out OpenPetra, download the Windows client at https://demo.openpetra.org and play with some non-real data!

I found now that the problem was already there in October 2016: https://github.com/openpetra/openpetra/issues/174#issuecomment-251063162

I was now able to fix it on the 64-bit Windows 10 Laptop:

download 'Microsoft Visual C++ Redistributable' version 2015 from https://www.microsoft.com/de-de/download/details.aspx?id=48145 - You need version 2015, an older version does not help.
I first tried the 64 bit version (x64), because the Laptop uses the 64 bit Windows. But that did not help. So you need to install the 32 bit version (x86).
