Version 5..8.6 on Debian 10 (Click New Simulation) -> Exception has been thrown by the target of an invocation

[Lucky]

Hi Daniel,

I have installed the latest linux version of DWSIM and have had issues getting it running. Each time I click on new simulation I get an exception. Could you please point me in the right direction for solving this? I haven't been able to find a solution through the previous forum/discussion threads. Here is the exception report:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.TypeLoadException: Could not load type of field 'Microsoft.VisualBasic.FileIO.TextFieldParser:m_PeekedLine' (11) due to: Could not resolve type with token 010000a6 from typeref (expected class 'System.Collections.Generic.Queue1' in assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089') assembly:mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 type:System.Collections.Generic.Queue1 member:(null)

Hi Lucky,

Did you install the latest mono version?

[Lucky]

I followed the mono installation procedures you posted onto youtube which allowed me to get vbnc. I was having issues downloading vbnc prior to that since it wasn't included in the debian repository.

Could this be an issue with vbnc?

HI Daniel,

I went through the procedure again and upgraded mono to version 6.8.

It seems to be working now.

I'm glad it worked. This is the first time I see an issue with mono-vbnc...

Hey Daniel,

I am facing the same problem with 6.3.7 (Debian10) and mono 6.12.00.90:

Is there a package missing?
Thanks a lot!

[Daniel Medeiros]

I think that you need to install a package which contains webkit for gtk3: https://github.com/picoe/Eto/issues/1304
