SigmaStudioPlus can not start

Could you please try this steps and let me know the status,

1) Uninstall the SigmaStudio Plus application

2) Clear all traces of SigmaStudio Plus folders

   a) Delete the folder, if not already deleted: C:\Analog Devices\SigmaStudioPlus-Rel2.0.0

   b) Delete the folder, if not already deleted: C:\ProgramData\Analog Devices\SigmaStudio 2.0

3) Clear all the contents of the folder: C:\Users\<user_name>\AppData\Roaming\SigmaStudio

4) And then, re-install the SigmaStudio Plus application

Thanks for your information. Now, my SigmaStudioPlus works after reinstallation. Something strange, it seems like that I launched CCES before lauching SSPlus, then, it works.  

The problem happened again. The following is the error log I found in folder C:\Analog Devices\SigmaStudioPlus-Rel2.0.0\Host, which is named "Error_2305231803.txt":

Is this issue happened when you are trying to import the SS schematic with custom blocks or only with SigmaStudio internal blocks?

You need to delete the custom blocks from SS schematic, save the schematic and generate the export files for porting the schematic to SS+.
Once the schematic ported to SS+ without custom blocks, you need to add custom blocks which is generated with SS+ algorithm designer.

Are you following the same step?

No, it happened when I tested with the example ADSP-21569 project of SS+. I don't know why the SS+ will crash. Could you find any problems from the log above?

Could you please create a technical support ticket in following link by describing more detail about this issue?

SigmaStudio Plus software having update on top of 2.0.0 release. Could you please update to newer version and try once? 

My installation package is named "adi_sigmastudioplus-rel2.0.0.exe". And the welcome UI is as below:

Since it blocked at the UI above. I can not open About menu to make sure about the detailed version of SS+.

How can I get the latest new version of SS+?

could you please disconnect your VPN if you connected to office VPN or any and try whether you are facing same issue?

I have double-checked the modules, and we have no customized module in the SS project. But the size of the project is more than 2MB. And it suspended after I tried to open the schematic in SS+. Why I can not open it? How many resources needed for running SS+ to open a big project? The following is the configuration of my PC:

CPU: Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz   2.71 GHz

RAM: 8.00 GB (7.86 GB usable)

OS: Windows 10 Enterprise (64-bit operating system, x64-based processor)

FreeSize of Disk C: 15GB
