I got the error when applying the update the reader was asking for.

• I am using Windows XP SP2
• I have Adobe Reader version 9.4.7
• The error message was just the number (1067) with a link to your explanation page.
• I have 26 GB free space on C:
• I have 4 gb RAM but XP only recognizes 3.25GB

The explanation page told me to download a new exe and install and post to this thread if it worked, which it did. I chose the english version of 10.1.2.

I just worked through this error on my Dad's computer.  He has XP Home SP 3, Adobe Acrobat 4 and Reader 9.4.7 were already installed. He has been getting to 1067 error for some time and just clicking through it.  I manually un-installed Acrobat 4,  but left the shared files in web/common alone.  I did not touch Reader 9.4.7. I downloaded the alternate installer for Adobe 10.1.2 for English and ran it.  It did complain, eventually, about 9.4.7 still having a file in use, but I'd left the previous dialog from the 9.4.7 updater failure open.  I closed that 9.4.7 failure dialog and hit 'retry', and the installer proceeded onward and seems to have completed successfully.

This machine has 1 gig of RAM and approx 4G of free disk space on C:. 

Hi,  I was getting the 1067 Error, after Adobe told me it wanted to install the newer software. That happened about 3 times before I noticed the 'find out more info' link, that brought me here. I downloaded the newer install file, and it installed fine.  I'm (still) running Windows 2000 SP4. I had received the 1067 Error, and something like "unexpected failure" to install message, previously.  I have 7.20 GB of space available on C:, after installing the newer V9.5.0 s/w. My laptop has 523,248 KB of RAM, according to System Properties.  I'm not sure what version of Reader I had before the install of V9.5.0, I think it might have been 9.4.7, but not sure.
