  Black hole-like objects with mass greater than $10 M_{\odot}$, as discovered
by gravitational antennas, can produce long time-scale (several years)
gravitational microlensing effects. Considered separately, previous
microlensing surveys were insensitive to such events because of their limited
duration of 6-7 years. We combined light curves from the EROS-2 and MACHO
surveys to the Large Magellanic Cloud (LMC) to create a joint database for 14.1
million stars, covering a total duration of 10.6 years, with fluxes measured
through 4 wide passbands. We searched for multi-year microlensing events in
this catalog of extended light curves, complemented by 24.1 million light
curves observed by only one of the surveys. Our analysis, combined with
previous analysis from EROS, shows that compact objects with mass between
$10^{-7}$ and $200 M_{\odot}$ can not constitute more than $\sim 20\%$ of the
total mass of a standard halo (at $95\%$ CL). We also exclude that $\sim 50\%$
of the halo is made of Black Holes (BH) lighter than $1000 M_{\odot}$.
