fatal error: Acrobat failed to connect to a DDE server.

i don't know why happening or changed on  machine, (admittedly) older toshiba laptop running windows vista. used able open pdf files read them, no problem.  today when  trying open pdf file, nothing happened. did ctrl-alt-delete , saw 20 acrord32.exe processes sitting there. if stopped 1 'image', 2 disappear. closed them , uninstalled called adobe air don't remember installing , uninstalled adobe reader.  tried 3 times download reader again didn't have luck because, apparently, using wrong browser. switched firefox, no luck. tried ie , worked, (ie 9.0.8112.16421, update version 9.0.14). installed download - slow, worked.

aha! thought. problem fixed. clicked on pdf in mail need review , nada.

tried open reader on it's own. nada. saved file c drive , tried open there. not nada... instead, got the  error message noted above.

 

the thing didn't do, guess, after install - have rebooted. somehow doubt fix while whole  crowd of (who waiting baited breath, sure, find out if problem solved) thinks problem might , answers in forum (which not searchable, btw, how odd!)... go that. come here , paw through 1000s of answers i'm sure waiting me.

i hope you're having better evening am. cheers!

ps: if said forum searchable, have tried find answer on own instead of perhaps asking question 7,010th time.

hi lissa,

 

please let me know version of reader using.

further after unisntalling adobe air have reinstalled it? try reinstalling adobe air , check.

 

there might many reasons error occur.

 

- might caused due file association error. make sure adobe reader default application view pdf's.

 

- able resolve issue acrobat x navigating to 

hkey_classes_root\acrobat\shell\open\ddeexec\application , changing key "acroviewa10"  to  "acroviewr10

of course before modifying registry please take backup beforehand.

 

- try starting following services in services.msc , check:

network dde dsdm

network dde

 

- check anti virus security policy , add adobe reader exception list , check.

 

- let me know log on properties of remote procedure call service, on computer giving error.

change setting 'log on as' 'local system account' 'allow service interact desktop' checked.

 

- try disable protected mode per instructions @ bottom of page: http://kb2.adobe.com/cps/860/cpsid_86063.html
