TouchGFX Designer Installation Error

Hi Everyone,

I'm trying to install TouchGFX Designer (v4.25.0) but I keep getting this error during setup:

“TouchGFX Setup Error writing to file: C:\TouchGFX\4.25.0\designer\TouchGFXDesigner-4.25.0.exe. Verify that you have access to that directory.”

I've already installed the following STM32 tools:

  • STM32CubeMX: C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeMX
  • STM32CubeProgrammer: C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer
  • STM32CubeIDE: C:\ST\STM32CubeIDE_1.19.0\STM32CubeIDE

I’m running the .msi installer for TouchGFX Designer, and the error appears consistently. I’ve followed both:

My installation directory is: C:\TouchGFX

I’ve checked permissions and tried running the installer as administrator, but no luck so far. Has anyone encountered this issue or found a workaround?

Thanks in advance!

    I recommend you to create an exception first.

    Helo @tejo,

    Is the folder empty ? Try to delete it before running the install. Also have you tried another install directory ?

    Hi!

    Thanks for answering.

    The folder "TouchGFX" is created during the installation process when i run the .msi file.

    When i get the error the folder is not empty. Also, I've tried differente directories: C:\, users, etc.

    But now i see the problem is related to a specific file that is flagged by the antivirus.

    I don't know if I should create an exception. Maybe I will try a earlier version of touchgfx and hope not to get the same error. What do you think?

    Thanks.

    Best,
