I have a similar problem using Windows XP. I already have Adobe Reader 9.0 installed and am trying to install 9.1. I get the same error message, but there are no open programs identified. (The message says to close the applications, but does not list any.) I tried re-booting, then downloading and installing before opening any other applications, but that had no effect.
FWIW, I ended up biting the bullet and killing off the only listed Windows Explorer process. As I expected the desktop icons and the taskbar disappeared, but the installation continued successfully.
You can then do a Ctrl-Alt-Del to start Task Manager and do File->Run and run explorer.exe to get the icons and the taskbar back, but personally. I'd rather reboot the computer.
Not so much a fix as a work-around.
Hope that helps.
Sorry ... this might result in a double post ... had to log in.
I'm a Mac guy trying to help a Windows friend with this same problem. Could you please be more specific on how to "kill off the only listed Windows Explorer process." We don't think we see anything running.
> We don't think we see anything running.
Use the Task Manager's Processes tab.
As Pat says, use the Task Manager's Processes tab...
Ctrl-Alt-Del then select Task Manager. Select the Processes tab and look for a process with an 'Image Name' of explorer.exe. Select it then click 'End Process'.
Your Desktop icons and the task bar will disappear, but don't panic, you should then be able to continue with the installation. After the installation reboot the computer and all should be OK.
I have tried three times to update to 9.1 on my PC with XP SP3. Each time, I get an error message that the "Program Manager" must be shut down. When I checked Task Manager under the Processes tab, no such program--or any other program, for that matter--was running.
I searched Microsoft Support for "Program Manager," and its replies alluded only to the "Utilities Manager," so even Microsoft doesn't know what Adobe is talking about!
(FYI: Utilities Manager is a feature for the visually impaired, which I don't use and didn't know I had.)
I've never had a problem with updates before. Any help would be greatly appreciated.
I tried ending the explorer.exe and then continuing with the install but still received the same error message. Any other ideas?
I followed Ryelandhill's advice and opened my task bar by using CTRL+ALT+DEL and went to the processes and ended process "explorer.exe" and that made Adobe download flawlessly. After it finished downloading i just did File->Run "explorer.exe" and everything reappeared. Although, it is kind of a ghetto work around it still works well and id reccomend using this method if you have the same problems downloading 9.0/9.1.
Edit: Well done Gary.
