Rocket build fails with mspdbcore.dll missing

Hey guys… i’m trying to create a rocket build for my plugin, and it won’t build anymore (something changed on my rig it seems)

The main error is this one:

    c1xx: fatal error C1356: unable to find mspdbcore.dllc1xx: fatal error C1356: unable to find mspdbcore.dll
    c1xx: fatal error C1356: unable to find mspdbcore.dll

Does anyone have any idea of what’s happening? i’ve tried reinstalling VS2017 but doesn’t work.
Cheers

Solved… had to install VS2015 toolchain from the VSInstaller and it worked.
