I have just downloaded Acrobat Reader X 10 to my laptop, which is running Windows Vista. When I try to open the program, either through the menus, or by trying to open a pdf document, I ger the message "An internal error occurred". No other information is contained in the error message.
I had a previous version of Acrobat reader that worked fine.
Has anyone else seen this, or have an ideas how to fix it?
Run this Microsoft Fix and then uninstall/reinstall Reader X again: http://support.microsoft.com/mats/Program_Install_and_Uninstall
