Microsoft's desktop project scheduling app. The process is WINPROJ.EXE. It is a separate SKU from Office. It is not Microsoft Planner.

What you need to know

Desktop Project is WINPROJ.EXE. Planner is a different Microsoft product.

Microsoft Project builds schedules in .mpp files. It is licensed apart from Office. Microsoft Planner is a web task board, not this executable.

Feex says

If WINPROJ.EXE is missing, I would check the Project SKU, not the Word installer. Planner in a browser is not this Gantt client.

What is Microsoft Project?

Microsoft Project is a desktop scheduler for Gantt charts, dependencies, and .mpp files. The Windows executable is WINPROJ.EXE. Planner and Project for the web are other Microsoft products.

If you have never used it

If someone sent an .mpp schedule, you need desktop Project, not Planner on the web and not Excel. Planner is a Microsoft 365 task board. WINPROJ.EXE is the Gantt and critical-path client. A Word-only 365 install will not include it.

What is it used for?

Gantt schedules

Tasks, links, and baselines in an .mpp file. Excel can hold a date list. It is not this scheduling engine.

Resource and cost plans

Assign people and rates. Planner boards do not calculate the same critical path.

Publish to Project Online or Project Server

Some orgs still save desktop files to a Project server. That is not a Planner bucket.

Who is it for?

Schedulers who live in .mpp files
PMs whose tenant bought Project Plan 3 or 5
Anyone who opened Planner and wondered where the Gantt went

Current status

Actively developed. Microsoft also ships Project for the web. This article is desktop WINPROJ.EXE.

How old is it?

Microsoft Project for DOS dates to 1984. It predates Microsoft 365 and Planner. Current desktop Project still uses WINPROJ.EXE. Project for the web is a different client.

Common problems

Project missing from Office setup

Microsoft 365 Apps that include Word still omit WINPROJ.EXE unless you add a Project plan.

People look for a Gantt in Planner

Planner is not desktop Project. Open WINPROJ or Project for the web, depending on the file type.

Getting unstuck

Confirm you have a Project license, not only Office

Project Plan 3 or 5 and Project Professional include desktop Project. Planner is included more widely and is not this exe.

Open an .mpp in Project, not Excel

Excel may import a table. It will not keep Project calendars and constraints.

Install from the Project product page after the admin assigns a license

Do not download winproj.exe from a filename site.

Alternatives

Planner, Project for the web, and a spreadsheet overlap for simple lists. They do not open every desktop .mpp feature.

Official help and downloads

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

Large schedules want RAM. A GPU does not shorten a critical-path calc.
