Everytime I download a document and try to open up a box opens up an says file conversion ms-dos word document (default) and some others as well. I've tried all and still will not work. There are a lot of letters and sybols that come up. whats the problem? I tried installing adobe and acrobat over and over .
You have to provide a bit more information than that. Your OS, your browser, what is causing that conversion - a browser extension?
If "something" converts a downloaded PDF doc to MS Word format, then that is not a problem of Acrobat or Reader.
Can you provide a screenshot of that po-up - perhaps we can find out what is causing that conversion.
