I had my PMDG, FSUIPC and many other addons under my addon  tab at the top of the screen.  I did a stand alone manager update to my Couatl products.  I went to do another flight and when I came back, all my addons are gone from the add on menu except ASN request, Add on manager and Couatl products.  Any thoughts?  I tried restarting the computer as well and still the same outcome. I use the saitek pro flight yoke and throttle so my FSUIPC is neccessary for all my profiles.  But the weird thing is where did all the others go.

been discussed already check these links out

I've read this and I'm not computer savvy. How do I go about this?

I was able to get my menu with my addons.  I only have one more question.  For some reason I have no FS Passengers menu to pull down.  There is no bar to pull down but I got all the other add ons to work.  I checked the dll.xml file and all the addons are in there except FS Passengers.  I don't know if it is suppose to be in the dll.xml file or not though.  Any suggestions?

Have you tried re installing fs passengers  again, or  if  you happened  to made  a back up of  your data/roaming/ folder  than you could  just simply  just copy  and paste  option the ddl.xml.  or  if  some  else has   fs passengers  they could  tell you the entries  you need  for  the ddl.xml

I did some searching and found a example dll text and copied the fs passenger entry into my current dll and it's now working. Thanks

good now   back up your ddl.xml  

In the folder that contains your dll.xml (same folder as the fsx.cfg), there usually are several backups of the dll.xml.  Everytime you install any FSDT or FlightBeam products, they make a backup.  So whenever you cannot see the Addon Menu in FSX (or P3D/FSX-SE) you want to look in this folder first for backups.  Of course, as suggested by Pete, it is always good to back up this file and I would suggest the whole folder periodically.  The AVSIM CTD Guide shows you have to edit the dll.xml so that only certain modules load up.

 

Best regards,

Yep whats even better  to make  a complete back up copy of  your hard drive  to a external drive ^_^

I had this problem yest, once you get everything back just make a backup copy of that DLL
