Hello, good morning.
I re-buy MAAM R4D/DC3/C47 to install it on a new computer ( Win7 64 bits and FSX Accélération Pack ) .
MAAM Installer 10th edition for FSX.
Everything works well ... but no altimeter in VC panel ...for some variant.
If this happens for you, I suggest to verify in panel.cfg , area [VCockpit04] and [VCockpit05]
line "gauge10" and rename Altimeter1, and Altimeter2.
For me it was the solution.
Best Regards
Yves
