Hi Andrew,

creating a new desktop shortcut is not the solution.

I made a test:

under my favorite UserAccount "Administrator":
de-install the installation manager, delete all relevant folders in bb/data, new install
- problem persists, InstallManager appears as a background process in task manager with HIGH power comsumption (!! ??)
- main.log ends with "[2023-12-10 11:00:55.776] [debug] (main) Creating Main Window"

under a different UserAccount "User":
de-install the installation manager, delete all relevant folders in bb/data, new install
- WORKS, InstallManager appears as a forground app process in task manager
- main.log is ident and continued with
[2023-12-10 11:06:34.110] [debug] (main) Creating Main Window
[2023-12-10 11:06:34.338] [debug] (main) Getting electron-is-dev for Renderer process
[2023-12-10 11:06:34.357] [info] (renderer) OS CPU architecure is (either x64 or x86): x64
[2023-12-10 11:06:34.359] [info] (renderer) process.arch (for which the binary was compiled): x64
[2023-12-10 11:06:34.360] [debug] (renderer) Creating config
.......
.......

Seems that InstallManager cannot create its main window under UserAccount "Administrator"
