Hi,

It looks like that the "RanorexStudio.exe.config" file is broken, could it be that you changed something in this config file?
Could you please post us your config file? We would like to analyze which XML code leads to this crash.

Attached is the original config file, you can use this one (just delete the txt ending before you use it) or you can repair the Ranorex installation in order to fix this issue.

Regards,
Markus

Hey Markus,

thanks for the reply, I have tried to repair and reinstall ranorex a few times.
and it did not help.

i did not change any setings during installing nor after it.

also i have tried replacing the config file, and it did not help.

Thanks,

Roy

Hello Roy,

Thank you for your config file. I looks still equal to the original file.
Would you please try to uninstall Ranorex completely from your computer. After that please check if all files from the Ranorex installation were removed.
After that, please uninstall all Microsoft Visual C++ Redistributables from your computer, restart your computer and try to install Ranorex again.
Please make sure that you use the Ranorex-4.0.1.exe or the setup.exe to install Ranorex.

Regards,
Bernhard

Hey Bernard,

Tried that, exactly as you asked,

Still getting the same exception.

Hi,

That's weird!
Which .Net version is installed on your machine?
Do you have sufficient user privileges to run/install Ranorex on your machine?
Was Ranorex started from a local drive or from a network drive?
Could you please try if it works with Ranorex 3.3.5?
Please use the setup.exe for the installation.

Thanks,
Markus

Hey Markus,

.net framework 4.5,

i have adminstrator rights on the machine,

installed from a local file,

tried the 3.3.5 (using setup file),

here is the error -

Hi Roy,

Thanks that you tried this!
This is a really weird issue, we haven't heard about such an issue before but we guess this could have something to do with some of your local .Net configurations.
What you could try is to comment out the sections about the log4net in the Studio config file.
Comment out this line "<section name="log4net" type="System.Configuration.IgnoreSectionHandler" />" and the full section about log4net: <log4net> ... </log4net>.
Are you able to start Studio after you edited it?

Regards,
Markus

Hey Markus,

comment it out.... and it worked.

wierd...

Thanks for the help

Hey Roy,

As we supposed it seems that the mentioned log4net configuration code already exists in one of the global .Net specific configuration files. This means that it is already defined and you therefore got the exception.
An easy fix is to just comment out the mentioned lines.

Regards,
Markus
