File conversion has failed due to invalid content that could not be read.

I am trying to convert pdf to a word but getting this error "File conversion has failed due to invalid content that could not be read."  I tried several other pdf as well but getting the same error message. I can open those pdf files without any problem.

Did you have any luck resolving this issue? I'm having the same problem with mine. Files convert using other PDF applications without issue.

Thank you.

Hello @Ghazanfar Ebrahimi,

Thank you for reaching out to us through our Community Forums!

In order for me to further assist you with your concern, could you please provide the following?:
-The serial number of your Nitro Pro. To send it via private message, hover your mouse on top of my name 'AllainU' and select 'Message'. This matters because our business installers are different from the online ones.
-Nitro Pro build (format is 13.X.X.X, e.g. 13.2.2.25) you are working with. You can find this out by clicking on 'About Nitro Pro' under the Help tab or you can go to Control Panel > Programs and Features.
-Does this happen with every file? If it is a single file, please send us the sample file (with sensitive information extracted) by sending me a private message so I can replicate it on my end. 
-A screen shot of the error message you are receiving and/or any important information. To find out how to take a screen shot, check out this link: https://kb.gonitro.com/knowledgebase/#/search/screen/000004108 

Thank you very much in advance and I am looking forward to hearing back from you.

I am also unable to convert files that used to convert easily. The following message is the reason: file conversion failed due to invalid content that could not be read

Hello @sjwc,

Thank you for the private message.

Since you are still working with an older build, let us try some troubleshooting by referring to these steps:

1. Clear the content of the directory under C:\users\your_username\Appdata\local\temp. For whatever reason, not all temp files automatically remove themselves and is NOT usually caused by Nitro Pro files. Kindly note Appdata folder is hidden and to unhide it, please refer to this article https://cybertext.wordpress.com/2012/05/29/cant-see-the-appdata-folder/ 

2. Download and run our Clean Up utility to uninstall your Nitro Pro:  http://install.nitropdf.com/professional_13241467/install-cleanup/install-cleanup.zip

NOTE: This clean-up tool will erase any existing signature files within Nitro so please save them to another location before using the clean-up tool in order to keep them. Please see this link for backing up custom stamps/signatures: https://kb.gonitro.com/knowledgebase#/search/stamps/000004307 

3. Clear all your downloads folder or delete all downloaded Nitro installers. This step is important because we noticed that if you are saving all the installers and you download them in the same folder (like the downloads folder), the EXE can pick up any MSI installer in that folder and you may pick-up one of the older builds instead of the newly downloaded package.

4. Download and install Nitro Pro 13.24 using below offline installers:

x32 http://install.nitropdf.com/professional_13241467/en/retail/nitro_pro13_ba_x86.msi
x64 http://install.nitropdf.com/professional_13241467/en/retail/nitro_pro13_ba_x64.msi

If you are not sure which to pick, this will help: https://kb.gonitro.com/knowledgebase#/search/64/000003790 

5. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering your serial number

Thank you for choosing Nitro and I hope this helps.

Thank you! All seems to be working so far. I had thought about uninstalling and reinstalling before I saw the question here. Thanks again.
