Adobe Acrobat Reader

ApplicationAdobe

Also called adobe reader, acrobat reader dc, acrord32

AdobeProductivity

Adobe's free PDF viewer. Classic 32-bit installs use AcroRd32.exe. Editing needs Acrobat or another editor. It is not Acrobat Pro.

What you need to know

Reader is the free viewer. Acrobat Pro is the paid editor.

get.adobe.com/reader is Acrobat Reader. Classic installs are AcroRd32.exe. A 64-bit unified Reader can share Acrobat.exe with the paid app. The About box and the Adobe account decide which product you have. Acrobat Pro is the sibling this page is not.

What is it?: Free PDF viewer
Can it edit pages?: No. That needs Acrobat or another editor
Process name?: AcroRd32.exe, or Acrobat.exe on 64-bit Reader

Feex says

If you cannot delete a page, I would treat this as Reader, even if Task Manager says Acrobat.exe. The free viewer is get.adobe.com/reader. The editor is a different purchase.

What is Adobe Acrobat Reader?

Adobe Acrobat Reader is the free PDF viewer. AcroRd32.exe is the historic 32-bit image. Acrobat Pro is the paid editor. If About Adobe Acrobat Reader is what you see, you do not have the editor.

If you have never used it

If you only need to open a PDF, this is free Acrobat Reader, not Acrobat Pro. Download it from get.adobe.com/reader. The paid editor lives at adobe.com/acrobat. Classic Windows Reader is AcroRd32.exe. Newer 64-bit unified installs may show Acrobat.exe even when you only have the free viewer. You still cannot edit pages until you license Acrobat.

What is it used for?

View and print PDFs

Open a syllabus or a form preview. Acrobat Pro is what you buy to rewrite the pages.

Fill some forms and sign

Reader can fill many fields. Creating or heavily editing a form is Acrobat.

Comment on a shared PDF

Sticky notes and highlights. Full organize-pages is still a Pro feature.

Who is it for?

Anyone who just needs to read a PDF
PCs that should not install the paid editor
People confused by a 64-bit Reader that shows Acrobat.exe

Current status

Actively developed. Adobe still offers a free Reader download. This article is the viewer, not Acrobat Pro.

How old is it?

Adobe shipped Acrobat and a free Reader together in the 1990s. Reader remains the viewer SKU. Acrobat Pro remains the paid editor. The 64-bit unified installer blurred the exe name. It did not merge the products.

Versions

Major channels first. Exact build numbers are not all verified here.

Reader 64-bit unified

Reader 32-bit (AcroRd32.exe)

System requirements

Values follow the publisher's public guidance. Workload still changes the real need.

Minimum

Minimum system requirements
Operating system	A current Windows release Adobe lists for Reader
RAM	Adobe lists modest RAM for Reader. Huge PDFs want more

Resource profile

CPU demand: Follows what you open inside the app
RAM demand: Follows documents, tabs, or libraries

Installed processes

These executables belong to this product when it is installed.

Installed processes
AcroRd32.exe	Classic 32-bit Reader. 64-bit unified installs may show Acrobat.exe with a Reader license
Acrobat.exe	64-bit unified Reader can use this image name. License still says Reader
AcroCEF.exe	HTML views

Startup components

Reader starts when you open a PDF if it is the default. Adobe updater helpers can stay resident. That is not proof you have Pro.

File locations

Common Adobe Acrobat Reader locations
Typical install	C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroRd32.exe

File formats

PDF

Common problems

Edit tools greyed out

That is Reader. Buy Acrobat or use another editor. Reinstalling Reader will not add Pro.

Optional McAfee or extra offers on the download page

Uncheck bundles on Adobe's official Reader page. A third-party "Reader download" is worse.

Getting unstuck

Read the About box

Acrobat Reader versus Acrobat Pro. If it says Reader, you have the free viewer. AcroRd32.exe is the classic image. Acrobat.exe can still be Reader on 64-bit unified installs.

Download only from get.adobe.com/reader

adobe.com/acrobat is the paid editor page. Filename sites that say "Acrobat Reader free" are a common junk path.

If you needed to edit, go to the Acrobat article

Do not hunt for a hidden Pro switch inside Reader. The products are licensed apart.

Alternatives

Sumatra PDF, Foxit PDF Reader, and Edge overlap for viewing. Adobe Acrobat is the paid editor sibling.

Official help and downloads

Start with the vendor. Random exe sites are not a support channel.

Official contacts
Download	get.adobe.com/reader/ Official installer or vendor page
Help	helpx.adobe.com/reader.html Vendor support
Official site	get.adobe.com/reader/ Start here, not a random exe host

Related hardware

The viewer is heavier than Sumatra. Huge scanned PDFs still want RAM.

Technical details

Vendor version numbers change. This article does not pin a build.
