I have researched this problem and still need help because I think my problem is different. First off, here's what happened...
I purchased and legally own CS4 Master Collection. I had it installed on my desktop. I ended up uninstalling Adobe Acrobat 9 pro. A week after doing that I had to do a system restore to a restore point BEFORE I uninstalled it. So the program obviously showed up again but with the error. Because of the error I uninstalled CS4 completely, thinking I could reinstall it again. Well when I went to reinstall, it already said that Adobe Acrobat 9 was installed already so I wasn't able to select it again to reinstall. All of the other programs installed just fine. And then when I go to try repair Acrobat 9, it doesn't even show as being installed with the other CS4 collection. And when I double click to open it, it does open and when I go to repair it, it will open up an installation box saying it's going to install and then gives that error 1311 saying the Data1.cab file is missing. And it is missing.
So my question is, how do I uninstall it when there's no option to uninstall it. Or how do I get the needed Data1.cab back in place to see if it will indeed install properly?
