Family Tree Maker won't install

Install errors look interchangeable and aren't. "Error reading from file" usually isn't a damaged download — it's leftover data from a previous install. Each message below has a different cause and a different fix, so start by identifying yours rather than trying everything.

Your existing tree is not at risk here. The tree file lives separately from the program, in a Family Tree Maker folder inside Documents. Installing, reinstalling and failing to install all leave it completely untouched. This is an inconvenience, not an emergency — worth knowing before you start.

Three Family Tree Maker installation errors with their causes and fixes: error reading from file means leftover installation data, another installation is in progress means a stuck Windows Installer, and error -132 means a corrupted download.
The three named errors at a glance. Schematic — shows where to look, not a picture of your screen. Wording varies by version.

Fix 1 — Restart properly, then run as administrator

Always first Clears a surprising number of failures

Five minutes

  1. Restart the computer — a genuine restart, not sleep or a shutdown with fast startup enabled. This releases a stuck installer process, which is the single commonest cause.

  2. Right-click the installer and choose Run as administrator. The installer writes to protected folders, and without those rights it can fail with no useful message at all.

  3. Pause your antivirus for the duration. Installers write many files quickly, which some security software treats as suspicious. Turn it back on the moment you're done.

Fix 2 — "Error reading from file"

Misleading message Clear the leftover ProgramData folder

Ten minutes · Your tree is unaffected

The wording sends everyone down the wrong path — people re-download the installer three times assuming it's damaged. It usually isn't. The installer is tripping over data left behind by an earlier installation.

  1. Close the installer and any running copy of Family Tree Maker.

  2. Open Windows Explorer and go to the ProgramData folder on your system drive. It's hidden by default, so either turn on hidden items or paste the path straight into the address bar:

    C:\ProgramData
  3. Find the folder containing the Family Tree Maker installation data and delete it. This holds installer bookkeeping, not your genealogy — your tree is in Documents and isn't touched.

  4. Run the installer again, as administrator.

Fix 3 — "Another installation is in progress"

Nothing is actually installing End the stuck msiexec tasks

Ten minutes

Windows Installer handles one job at a time. When a previous one didn't finish cleanly it stays latched, and every new installer is refused. Waiting achieves nothing, because nothing is going to complete.

  1. Open Task Manager with Ctrl + Shift + Esc.

  2. Find every running msiexec.exe task and end all of them. There's often more than one.

  3. If they won't end, look for the Windows Installer service (msiserver) in the services list and restart it.

  4. Simplest alternative: restart the computer, which clears the whole thing. Then install before opening anything else.

Fix 4 — "Error -132"

Usually the download Get a fresh copy rather than reusing yours

Twenty minutes

  1. Download the installer again from the publisher. Don't reuse the file you have — a partial or interrupted download is the likeliest cause, and it looks identical to a good one.

  2. Check free disk space. An installer needs room for both the download and the unpacked program, which is more than people expect.

  3. Clear temporary files before retrying.

  4. Run the new download as administrator — the other half of this error is insufficient permission.

If the installer won't download or won't start

  • The browser may be blocking it. Installers are commonly flagged. Check your downloads list for a blocked file and allow it — but only for a download you fetched from the publisher yourself.
  • Security software may have quarantined it before you ever saw it. Check the quarantine list.
  • Try a different browser if the download stalls repeatedly.
  • Never take an installer from a search result or a third-party download site. That's how people acquire something other than what they wanted. Only the publisher's own download is safe.

Fix 5 — Install from a clean boot

Last resort Removes everything that could interfere

Thirty minutes

A clean boot starts Windows with a minimal set of drivers and startup programs. If something in the background has been quietly breaking the install, this removes it from the equation.

  1. Configure Windows for a clean boot and restart.

  2. Run the installer as administrator while in that state.

  3. Set Windows back to a normal startup afterwards. Clean boot is a diagnostic mode, not somewhere to leave the machine.

  4. If it installs in clean boot but not normally, background software was the cause — worth knowing for next time.


If it still won't install

  • Try a new administrator user account on the machine. If it installs there, your profile is the problem rather than the installer — the same technique as in the startup guide.
  • Find your registration key first. You'll need it, and hunting for it later with no working software is a miserable hour.
  • Licence, key and download problems belong to the publisher. They can reissue a key against your purchase record — that request goes to them, not to us.

We'll read the installer log with you and find where it's stopping. If we can't get it installed, you don't pay.

Making the next install easier

  • Keep your registration key somewhere you'll find it — printed, or in a password manager. Not only in an old inbox.
  • Back up before upgrading, with media included. See backing up properly.
  • Uninstall cleanly rather than deleting the program folder, which is what leaves the ProgramData debris behind.
  • Note which version you had. Useful if you ever need to go back.
  • Only ever download from the publisher.

Frequently asked questions

Will a failed installation damage my existing family tree?

No. Your tree file lives separately from the program, normally in a Family Tree Maker folder inside Documents, and installing or reinstalling doesn't touch it. A failed install is an inconvenience, not a threat to your research.

What does error reading from file mean during installation?

Despite how it sounds, it usually means leftover data from an earlier installation is confusing the installer — not that your download is damaged. Removing the old Family Tree Maker folder from the hidden ProgramData directory and running the installer again clears it in most cases.

Why does it say another installation is in progress when nothing else is installing?

Because Windows Installer is stuck rather than genuinely busy. Ending every running msiexec task in Task Manager, or simply restarting, releases it. Waiting doesn't help — nothing is going to finish.

What causes error -132 in Family Tree Maker?

Usually a corrupted installer file or insufficient permissions. Download the installer again rather than reusing your copy, clear temporary files, check free disk space, and run the new download as administrator.

Do I need my registration key to reinstall?

Yes — find it before you uninstall anything. It was issued at purchase, usually by email. If it's lost, the publisher can reissue it against your purchase record. That request goes to them, not to us or any other third party.

Should I turn off my antivirus to install?

Pausing it during the install is reasonable — security software commonly interrupts installers that write many files quickly. Turn it back on the moment you're finished, and only ever pause it for a download you got from the publisher yourself.
