Adobe Acrobat Pro XI not opening

Hello,

We have a user who began complaining that Adobe was giving an error "Adobe failed to send a DDE command" when trying to open a file or open directly.

I confirmed this.

I tried all of the following: I ran a repair, I tried opening it in various compatibility modes, I tried uninstalling possible conflicting software, I tried it on a different user, I tried disabling AVG, I tried tinkering with the registry, I tried a reboot, I tried a modify.

After the repair it refused to even give the warning. It would just open briefly enough to see it appear in the task manager and then disappear.

Nothing worked

It opens briefly then closes. He had installed Adobe Flash that day and it was working after that for a while so I'm not sure the issue is connected (I uninstalled it anyway to no avail)

Does anyone know what to do?

We cannot reinstall as he doesn't have the serial and I couldn't find it with Produkey. Are there any product key readers you know of that you trust that would find it?

Thanks for any and all help!

Hi

These are really difficult to diagnose. Hence most people go for uninstall and reinstall.

You can try the following first though.

Locate the Adobe Acrobat folder in Program File(x86), search within that for the plug_ins folder. If you have a working Acrobat setup on a different PC compare the folder structures and rename the different ones on your (offending) PC. If you have nothing to compare to, rename your plug_ins' subfolders one by one, checking after each rename (and restoring of previous names) if the problem persists. That way you can isolate an offending plug in.

Thanks I had hoped that there would be a quick easy answer as that huge task was the thing I was trying to put off! I'll get onto it though, thanks for the advice.

I'm sure it's a plugin too.
