All my products apps are not showing!

I have an extra driver for memory where I installed all of my Adobe products. However it tends to be glitchy and crash and even though the driver's plugged in data is not being transfared, as if it's not connected. I was trying to update Premier Pro and I got a bunch of error messages so I restarted my computer. Because of that my adobe products are missing as if they're not installed even though I managed to make the driver work again. Even a restart didn't help.

What should I do?
