After some problems with the Vistamare (Vimacore) library caused by a dll.xml malfucntion, now resolved (missing some lines at the end of file), I noted that LSZH have only aircraft and not buildings, etc,. I have in FSX menu both addonmanager and couatl menu working normally. Since in the addonmanager LSZH was "outdated" I decided to uninstall it (without uninstall addonmanger and couatl) and reinstall with the same installer (ver 1,5), as result: the same in LSZH, but also in KORD that before LSZH uninstall was working normally. I've installed then also the new standalone installer for addonmanager, but nothing new. I noted that also KORD was "outdated" (intaller version1.3), but, since these bad results with LSZH I decided to make nothing for this.
So:
both LSZH and KORD are withour buildings and structures, but all other my FSDT airports (KJFK, KFLL, PHNL) are OK: , fsx menu addonmanager and couatl always OK.
Note that also, like indicate here in the forum, I've deactivated, before all reinstall, antivirus and excluded bglmanx.ddl and couatle.exe from scanning!
What else to recovery buildings for LSZH and KORD, before have other surprises ?
Thanks in advance , squalo
