I have trying shreya’s aab tool to change my APK to aab. But aab tool not opened. There I got the error message of " to run this application, you must install .NET Core but I have installed .NET Core.
I installed python version 3.7 java 8.2
Help me to solve this issue
Download .NET Framework 4.5 | Free official downloads (microsoft.com)
Download runtime exe and try again
Download runtime exe and try again
Not installed this one also.
see the error messages 
.net framework already in operating system but aab tool requires .net . what should i do?
I pm you check it
whenever i get time i will make Self contained application so we don’t need to download .NET Core
It would be nice to post the solution here in case anyone else faces the same problem
I said him to change Net core version from 4.5 to 3.1 but still same error coming 
if problem get solved i will update this post
Edit: problem was 32bit net core runtime was installed on 64bit windows 10
now it working after installing 64bit net core runtime for windows 10 64bit
Now aab tool open… But not started to change APK to aab
Find the attachment
Why you add “edited aab” in the last of folder path ??
Just select folder only application will automatically add a name to generated aab file
