Title: PatchMyPC creates a copy of itself in c:/users/ when updating, causes errors
Post by: waylo on October 05, 2025, 08:49:13 PM
I previously posted here on the support forum about an odd occurrence of Patchmypc creating a copy of itself in the C:/users/ folder, that is named after the first string of my username.  The fact the file is there causes Windows to run the renamed executable (Patchmypc) several times upon booting, or waking from sleep.

I now have a log that documents why this happens.

This occurs with the portable version, and it occurred every time PatchmyPC attempted to update itself.  It began happening several days ago when I believe the update to 5.3.1.0 came online.  The patchmypc executable is in c:/users/myusername 2/desktop

When I closed and restarted the program, the identical sequence appeared:

I believe this is a bug as the updater should not be creating a renamed copy of itself to be placed in the c:/Users/ folder.

My username follows the format "Myusername 2".  I wonder if this format throws off the parsing for the update process.

I have another computer with a single string username that did not have this issue upon updating.

Hi @waylo,

Thanks for reporting this issue. The root cause is that the updater currently trims the path at the first space character, which leads to the update process failing.

We are actively working on a fix. In the meantime, you can use one of the following workarounds to stay up to date:

Option 1: Download the latest portable version from our website (https://homeupdater.patchmypc.com/public/PatchMyPC-HomeUpdater-Portable.exe)
Option 2: Temporary workaround
1. Move the app to a directory without spaces in the path (e.g., C:\Apps\PatchMyPC-HomeUpdater-Portable.exe).
2. Open the app and go to the About page.
3. Click the Check for updates button and allow the app to perform the update.
4. Once updated, you can move the app back to your preferred location.
