Who This Affects and What Fixes It
This article is for Windows users whose Inkscape installer stops and will not proceed because an older or partially installed version of Inkscape is already on the computer. The fix is to fully remove that existing version—using Windows Settings and, if needed, Microsoft’s Program Install and Uninstall Troubleshooter—then restart and reinstall Inkscape.
Why This Happens
The installer blocks because Windows still has a record of a previous Inkscape installation. This is usually caused by one of the following:
- A corrupted uninstall that left files or registry entries behind
- A hidden Windows Installer entry that was never fully cleaned up
- A previous version that was not completely removed
Step-by-Step Fix
- Open Settings, go to Apps, then select Installed Apps.
- Find Inkscape in the list. If it appears, uninstall it.
- Restart your computer.
- Try running the Inkscape installer again. If it still fails, continue with the steps below.
- Download and run the Microsoft Program Install and Uninstall Troubleshooter.
- When prompted, choose Uninstalling, then select Inkscape from the list. If Inkscape is not listed, choose Not listed and follow the on-screen prompts.
- Restart your computer once more.
- Reinstall Inkscape 1.4.3.

Common questions
Why does the Inkscape installer say a previous version is already installed?
Windows still has a record of an older Inkscape installation, even if the program appears to be gone. This can happen when a previous uninstall was incomplete, leaving behind hidden installer entries or leftover files that block the new installation.
What is the Microsoft Program Install and Uninstall Troubleshooter and where do I get it?
It is a free tool from Microsoft designed to fix problems that prevent programs from being installed or uninstalled correctly. Search for ‘Microsoft Program Install and Uninstall Troubleshooter’ on Microsoft’s website to download it.
Do I have to restart my computer between steps?
Yes. Restarting after each uninstall attempt allows Windows to fully clear any in-use files or processes tied to the old Inkscape installation, which is necessary before the new version can install successfully.
