Adobe Acrobat
Can I change a "read only" file from Adobe to a word document?
An Adobe Premiere video editing project file would usually have a .ppj extension.
Yes, if you have Adobe Acrobat (not the free Adobe Reader) installed on your computer. There is also 3rd party software that will convert the .pdf file extension to a file type you can edit without purchasing Adobe Acrobat.
It sounds like the file you are trying to read has become corrupted somehow. Or there is something wrong with your Adobe installation. Try reading a different pdf file and see if it works, if it does, then the first file is corrupt. If not, reinstall Adobe.
Portable Document FormatPDF is a file format within Adobe Acrobat. Any file with an extension of .pdf can be opened with Adobe Acrobat.
I tried to open a file using Adobe Reader 9 from an email and it wouldn't work. I thought that saving the file and then opening it from Adobe Reader might work so I saved the file. I tried to open Adobe reader but it would not open at all. I then tried to reinstall adobe reader but it would not install on my computer... HELP!
