Installation Error invalid type code: 00

I recently downloaded the MicroEJ Studio (Win64 which should be compatible with my computer) from the official website. The installation was ok except for this invalid type code: 00 Error I nomarlly get even after reinstalling the app multiple times.
This is what I get when I click on Show Details :

At a point I decided to procced with running the application but that fails with a logged error.

Dear @callistus,

Can you specify the version of Windows you are using?

Regards,

Pierre.

Im running windows 7 professional 64bit with 64bit jdk…

Hi @callistus,

Can you do a sha1 of the installer? You should get 7f6c737ea7551810afaf1b092b0dce97c8c93896 for the installer 4.1.5 Win 64.

Regards,
