ops centre giving an error of " not a valid win 32 application. unable to run updater.exe" message and quitting.. anyone facing this? any solutions please?

Try to reinstall the application with Admin rights (run as admin) and disable your anti-virus for installation.

Just keep trying, close the ops and try again.  I had this problem this morning and i just kept running it again and succeeded to install update 1.4.

not happening tried 10-15 times closed and ran the ops centr again! no luck! still not valid win 32 app..  how to reinstall just ops centre again without reinstalling 777? if I reinstall then wont i use up the number of reactivations possible?

Try to remove OpsCenterUpdater.exe from C:/ProgramFiles(X86) PMDG Operations Center and launch ops again, does it help? I think there is no separate uninstaller for Ops Center so you would have to uninstall 777 to get Ops center installed again...

BINGO!! thanks a lot buddy!! Happy landings!

there is no separate ABNORMAL section in FCOM 1...any ideas? any document/tutorial/utube video that will make the EICAS NNM chkl /callout handling easier?

But anyway, your updater is broken and should be replaced/fixed

Well, i think it is replaced by new updater when we update the OPS Center so problem solved so far....

why is the updater so slow..it takes 15 mins to update just 5-6 MBs!!

Maybe the Servers are at high capacity

That might be the reason
