I've repaired Adobe Acrobat Pro DC. I then uninstalled and reinstalled but the prelifght panel won't open. All the other panels in the Print Production tool do open, but not preflight. You can see that it looks like it's activated, but that's it (see image). Hopeing someone can help. Thanks.
Hope you are doing well and sorry for the trouble. As described the preflight panel wont open and you have tried repairing and removing and reinstalling the application with no luck.
Would you mind sharing the version of the application you are using? To check the version go to Help > About Acrobat and make sure you have the latest version installed go to Help > Check for updates and reboot the computer once.
Please try to reset the Acrobat preferences as described in the help page https://community.adobe.com/t5/acrobat/how-to-reset-acrobat-preference-settings-to-default/td-p/4792... and see if that works for you.
Also, please try to create a new test user profile with full admin rights in Windows or enable the root account in Mac and try using the application there and check.
If it still doesn't work, please remove the application using the Acrobat cleaner tool -https://www.adobe.com/devnet-docs/acrobatetk/tools/Labs/cleaner.html reboot the computer and reinstall the application using the link - https://helpx.adobe.com/acrobat/kb/acrobat-dc-downloads.html
Version is 2021.0005.20060
I did the preferences, no luck.
I can't test a new user profile. I think it's my machine, I tried it on another and it works.
I will need to contact our IT department. Do you have any further suggestions for them?
As mentioned its working on a different machine and not yours. Also as its a work machine managed by IT, please get in touch with the IT team at your end and see if that helps.
Since the Preflight window is a floating one, and not docked to the application window, is it possible that it is open, but on another monitor - maybe behind another app?
Thanks Dave, but sadly this is not the case.
Worth a look - I've lost dialog boxes behind windows for years!
Wondering if there's been an update with this issue from anyone else.
I was running into the same problem just today. I had a different installation which had this problem and which I didn't want to renew, I figured I might as well switch over to my school's enterprise account. I followed their instructions, and I ended up downloading version 2022.001.20117 via Adobe Creative Cloud Desktop as part of the enterprise account provided by my school. I noticed the issue persisted in this version as well, and came to googling for this issue and stumbled across this thread.
I went into the article mentioned by AmaL, https://community.adobe.com/t5/acrobat-discussions/how-to-reset-acrobat-preference-settings-to-defau... , and not only did I delete the folder in Roaming, but I went back to C:\Users\[username]\AppData\ and also went into the Local and LocalLow folders, which both should have an Adobe folder containing a child "Acrobat" folder (probably more user preference and cache files stored there). After deleting all three associated Acrobat folders (in Local, LocalLow, and Roaming), I re-opened Acrobat DC and Preflight was working.
Not going to question the specifics or even what specific file/folder was causing the error, but all I know is deleting those preference/cache folders in my AppData folder worked for me.
Let me know if this is helpful to anyone who happens to stumble across this same issue.
I noticed the same issue today, on a perpetual license of Acrobat 10 Pro. I deleted the following folder and Acrobat started working correctly again:
C:\Users\[username]\AppData\Roaming\Adobe\Acrobat\Preflight Acrobat 10
