Solved Unable to implement a additional parts pack for a brickbuilding program.

Hi i'm new here. I'm not in good at introductions online, on top of that this problem has but me in a bad mood nearly all week

I've recently installed a brickbuilding program called Studio. It has the ability to install part add-on pack and i've done it before on a windows 10 in the past but this one pack is unable to do it despite i was able to install other two parts packs. I have followed the manual instructions and yet the parts don't show up under custom parts folder.

Here is a image...my system is windows 11 home edition on a Asus laptop
specifications are included ASUS X541 - Tech Specs｜Laptops For Home｜ASUS Global

Since the installation of the add-on has no executible file (.exe) and all you do is drag and drop the files into your Studio folder, it really is not a Windows installation.
Verify that the files indeed copied over to your Studio folder correctly. If they did, then I would think there is some discrepancy in the files themselves, some corruption in the application, or the application/or add-on is not compatible with Windows 11. I would contact Studio support.

Managed to fix it. The manual installer seems to be obsolete but i managed to find a automatic installer.
