Error when trying to open Mendix Studio Pro

0
Hi all, When trying to open Mendix Studio Pro (both version 8.0.0 and 8.1.1) I get the following error. First got the error when trying to open 8.1.1 and thought it was because the app I was trying to open was build under 8.0.0. Then after downloading 8.0.0 I got the same error. It also occurs when trying to open Mendix Studio Pro straight from desktop. Has anyone else experienced this?       Details:  SimpleInjector.ActivationException: Could not load file or assembly 'System.EnterpriseServices.Wrapper.dll' or one of its dependencies.  is not a valid Win32 application.

Update: The error continues to occur even after re-install.

One option is to remove your project and redownload the most recent commit of your project. Or download one commit before that in a new branch. See if that resolves the problem.

Otherwise report this as an issue at support.mendix.com, like the error message advises you to. You should probably do this anyway because this bug needs to get resolved.

From the release notes:

  • We removed support for running Studio Pro on 32-bit systems. Studio Pro now runs only on 64-bit systems.

I have a 64-bit system and both 8.00 and 8.1.1 worked fine last Friday.

Hello Koen,

This post https://stackoverflow.com/questions/2890773/system-enterpriseservices-wrapper-dll-error suggests that restarting your system can help. Can you try that?

It might be a problem with the .NET installation. Can you try repairing or re-installing that?
