Engine not installed, cannot acquire marketplace asset

Downloaded and installed UE in 4-6 hours, due to slow internet.

Error at the end but i managed to run it from the UEeditor.exe
but it never says it is installed, and fails to do so regardless of what i do.

Because of lacking graphic card, i moved the data to
a new laptop, 4.11 folder, launcher and the entire epic game folder to a similarly placed and named folder.

problem is: i cannot download any marketplace data,
it keeps telling me to redownload the engine from my profile.
I tried various solution like using echo at the cmd.exe, or using version selector on 4.11, or change the shortcut with -opengl.

Help!
I need to use aome.marketplace asset!
