Update Adobe Acrobat Pro X to the Latest Version
Updating Acrobat to version 10.1.10 patches known compatibility bugs between the Adobe browser plugin and Internet Explorer.

Follow the on-screen prompts to download and install the latest patches until you reach version 10.1.10 or higher.
Close and reopen Internet Explorer, then try loading the PDF preview again.

Frequently Asked Questions
Why does Internet Explorer block certain PDF previews?
This typically occurs due to outdated Adobe Acrobat browser plugins, strict security settings in Internet Explorer blocking active content, or internal corruption within the specific PDF file.
Can I view PDFs without using a browser plugin?
Yes. You can use standalone desktop applications like WPS Office or Adobe Acrobat Reader to open and view PDF files directly, which bypasses browser restrictions entirely.
Is Windows 7 still supported for Adobe Acrobat X?
Adobe Acrobat X is an older version and has reached the end of its official support lifecycle. Upgrading to a modern PDF solution is recommended for better security and compatibility.
What should I do if printing to Adobe PDF doesn't fix the corrupted file?
If recreating the file via the PDF printer fails, try opening the original source document (such as the Word or Excel file it was created from) and exporting it as a new PDF.
