I upgraded to Reader 11.0.2 and it wouldn't open any pdf's. I tried the troubleshooting steps, none of which worked and then tried to uninstall and re-install. Now I can't re-install any version of Reader.
Any help much appreciated.
So you get that error even if you try to open Adobe Reader by itself?
Can you try to disable Protected Mode by downloading, extracting, and running the attached registry script?
Yes I get this error message even when I try to open Acrobat Reader by itself. I've tried running the script but this doesn't make any difference. Is there any particular folder I should place this in to run it?
I've just re-installed Reader XI and it opens fine now. I still seem to get the message above after a minute or so but if I just click on "don't send" the message goes away and the application continues to function, so hopefully it's nothing more than a minor annoyance.
I ran into this same problem and was able to solve the problem. (Both for Adobe Reader X and Adobe Reader XI).
I'm using a laptop with NVIDIA video card and discovered that the NVIDIA Video Driver was somehow conflicting with Adobe Reader XI's EULA.exe program, which runs first time after install.
drunmi: this is exactly what's happening to me, and thank you for pointing it out. I'm still having problems because I don't have a driver update in my recommended updates list, and don't see that I updated the driver in the March update you talk about. I also don't see my particular driver at NVidia's driver site, and don't know enough about how the thing works to have the guts to download a different driver than what I currently have (they're recommendation). Very frustrating for me thanks to my limited computer knowledge.
Anyway, thanks again. At least I can see that there's certainly a conflict occuring between the NVidia dll file and Reader XI. When I try to start XI, it begins to open, stays gray for about 5 seconds, then disappears. I think it's as you say, that I still haven't approved the EULA (which I can't because it's conflicting with the graphics driver).
Very frustrating for a barely-competent computer user.
I was having this exact problem. See the reply by drunmi below. I used his steps to see if my NVidia graphics driver was conflicting with Adobe XI's eula.exe file (end license agreement you have to agree to prior to reader opening). It was. Downloaded a newer NVidia driver. Adobe XI's EULA opened, accepted. Now Reader's working.
Thanks so much drunmi. I've seen numerous other threads on this strange problem. I went as far as downloading a different reader just so I could print out a much-needed document. Thanks again.
The NVidia vs EULA conflict does seem a possibility for me, too... I'm currently trying to update NVidia. Unfortunately Java isn't allowing the automatic NVidia scan so I've tried it manually and some options are there... we'll see what happens...
I have had latest version of Java (installed and) enabled in my browser(s) for some time. However, security messages suddenly (within the last few days) started blocking Java. Therefore, in Java control panel > Security tab, I added relevant websites to the Exceptions Site List. That worked... Nvidia was then able to detect a driver update. The download failed to complete; I tried again, got another fail message plus instruction to restart... but I seem still to have the old driver.
