Installation error on PS 1.7.7.0

[technik_16001]

Hello there,
I have problem to install agilemultipleseller-3.7.4.0 on Prestashop v 1.7.7.0.
agilekernel-1.7.1.6 has been installed successfully as first.

Error message within module installation:

Exception:
You are not allowed to disable the module agilemultipleseller.
