Hi Anand,

I was just going to start working through the troubleshooting links you sent and the Adobe updater just ran and installer an update of some sort. Now when I launch Acrobat it all works again, so I think they have done a fix somewhere Fingers crossed it carries on working

Many thanks for your assistance.

Hi Anand,

Ok, I will try your suggestion and let you know.

Acrobat has been working since install last year and the error message only appeared about 2 weeks ago, so something has changed and caused this

Hi Paulw,

Please try the steps below and let me know if that worked-

1. Do you have the Preview Pane enabled in File Explorer? If so, can you disable it temporarily to see if the problem goes away? On Windows 8, in Explorer go to the View tab, and if the "Preview Pane" button is pressed, un-press it. On Windows 7, towards the top-right (towards the left of the help icon) there's a "Show the preview pane" button; un-press it.

2. Make sure the following directories exist on your machine. If not, please create them:

C:\Users\USERNAME\AppData\Local\Adobe\Acrobat\DC\ToolsSearchCacheAcro

C:\Users\USERNAME\AppData\Local\Adobe\Acrobat\DC\ToolsSearchCacheRdr

Hi Anand,

I am using Windows 10 Pro and the preview pane was off anyway so I made no change.

The first folder you mentioned already existed, but the 2nd one did not, so I created that one.

Note, on my laptop, where you say in the folder path \DC\ mine says \2015\

I then re-installed the program, but there is no change. Acrobat launches and the Welcome screen is present for 3 or 4 seconds then the program just closes.

Please reset the Preferences settings in Acrobat, follow the steps from: How to reset Preference settings in Acrobat.

If possible, Please try to launch the Acrobat Pro DC in a new user profile, i.e. Create a new user profile and check.

Hi Anand,

The link in your message didn't have a URL, but I found this topic in one of the forums. I moved the UserPrefs folder to a new Temp folder in the root. Tried a new user, administrator and myself and no change. The program launches with the welcome screen then immediately closes with no warnings/errors.

Please use the cleaner tool to remove the Acrobat Pro DC, and reboot the computer, and then reinstall the software from the link which I shared.

Keep us posted with the result.

Hi Anand,

I have done this and now it does something slightly different. The program launches and you can briefly see the welcome screen, then it immediately closes. There are no error messages or warnings now to give you a clue as to why it it failing. Any ideas ?

Hi Paulw,

As per the description above, you are not able to install the Acrobat Pro DC as getting error code 50, Is that correct?

Please uninstall the Acrobat Pro DC using the Cleaner tool: Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs

Then restart your computer, and reinstall the Acrobat Pro DC: https://helpx.adobe.com/acrobat/kb/acrobat-downloads.html

Keep us posted with the results.

Hi Anand,

Acrobat DC Pro has been working fine since original install over 1 year ago, but now comes up with error IMSLib file missing and tells me to go to adobe.com/go/applicationmanager, so I do this and download Creative Cloud app manager, but when I try and install this it comes up with Error 50 and stops.

I've tried unistalling/reinstalling using Windows installer so now I shall try the links you mention and see if this fixes it.

Paul
