Hi! I had installed the RC4 version of Corona 4. Now that I have installed the released version, I cannot open max anymore. It happens both in Max 2019 and max 2020. It stops CoronaUtils2019.dlt and same for max 2020 (coronaUtils2020.dlt). I have uninstalled Corona and tried installing it again, but same thing happens. Please help! ---

Hi, Which language is your Windows version set to? We are aware of an issue with launching Max in versions of Windows in some languages. Please try setting it to English and see if this helps. Thanks, Rowan ---

Hi, In this case can you please generate a minidump from Max so we can work out what is going on? Instructions on how to generate a minidump are in my signiture, you will need to follow step 2. In the meantime, can you try checking that your region settings are also set to English? Thanks, Rowan ---

I changed Region to english, that didnt help any. I’m unable to make a minidump because 3ds Max doesn’t even boot up. the error happens in loading the program and then 3dsmax is only listen in background processes and not shown in Process Explorer. ---

It is not enough to change the region. You need to change the locale to United States. ---

Let’s try a different approach: try renaming the C:\Users\AppData\Local\Autodesk\3dsMax\ENU folder and starting Max again. ---

We’ve had a Team Viewer session with Joachim. We did not manage to solve the issue, but we got Corona 3 to work. I captured a minidump and we will investigate this. ---

Hi, So this could be a few things. Did you install Corona using the installer or using the unpack option? If it was the unpack option you will need to install the latest microsoft redistributables from [here](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads) Secondly, what are your current language and locale settings? As this could also be to do with your language and locale settings. Could you please try setting them both to English and see if this helps? Thanks, Rowan ---

I already tried all this. It’s the same results. When I open 3ds Max and get to charge Corona gives error. ---
