This is a DC Pro subscription running on Win 7 Home Prem SP1 64-bit. Acrobat loses my login info about 75% of the time when I close the program and reopen, with or without restarting or logging out of my pc, annoying but workable. Sometimes the save icon on the toolbar is invisible. I wasn't able to get a screenshot, but the button is clickable and works despite not displaying, also annoying but workable. Then, mid-session, as seen in the attachment, all Adobe icons converted to placeholders. First, I attempted a repair, then an uninstall. Both attempts yield the same error, "Error applying transforms. Verify that the specified transform paths are valid," as shown in the attachment. A quick search referenced MSI & transforms, but that is beyond my skill level. I haven't a clue what to do about this and would like to address it before other issues occur.
