Adobe Acrobat Has Encountered An Unknown Error

When trying to edit text (by clicking Tools Content Editing Edit Text and Images) a message saying 'Acrobat has encountered and unknown error' appears. I have also tried selecting the text prior to going through these steps, but the same message appears. Adobe Acrobat 9: No PDF file was created because Acrobat encountered an unidentified error; this error occurs when user tries to combine files from a network drive. It works if you save everything locally; however, user is working with hundreds of files - very cumbersome to have to copy everything locally. If you still see the error, use the Adobe Reader and Acrobat Cleaner tool to remove traces of any previous installation, and then reinstall Adobe Acrobat Reader or Adobe Acrobat. 1618: Another installation is already in progress. Complete that installation before proceeding with this install. Another install is in progress and MSI is busy. Adobe support; Acrobat DC FAQ; Contact Adobe support; Resources. When I try to edit or add text always the sdame failure occurs: acrobat has encounterd an unknown. Select the Touch Up Reading Order tool. Select the Show Tables And Figures button. If the table is not clearly labeled in the document pane, drag to select the entire table, and then click Table in the dialog box.
